Detailed Description
In the conventional technology, the following two print data adjustment schemes are usually adopted to meet different print display requirements of a client under the same set of service data:
<1>, print plug-in intervention scheme: the business developer adjusts the printing data by specifically developing the printing plug-ins supported by the enterprise application system. <2>, print data readjustment scheme: utilizing a third-party tool to perform simple calculation adjustment on the data displayed during printing; for example, the enterprise application system binds fields under the document field model through an Excel template to generate a print Excel file, wherein the Excel template can readjust print data by using a library function of Excel.
Although the two schemes can meet different printing and displaying requirements of customers under the same set of business data, the two schemes have the defects aiming at enterprise application systems:
<1>, print plug-in intervention scheme: the business scene of the enterprise application system is complex, and the printing scene is the same, so that when each document needs to be printed and intervened by a plug-in, a large amount of labor cost is consumed by developers to carry out corresponding matching adjustment. <2>, print data readjustment scheme: due to the complicated document data, part of business logic cannot deeply intervene, for example, a third-party tool Excel has difficulty in filtering out some printing fields.
In the embodiment of the present application, a dynamic field is understood to be a virtual field that is dynamically calculated during adjustment of print data, and has both information of a calculation expression and a field identifier (referred to as a dynamic field identifier). An expression reference field, which often refers to a field name that can be directly obtained by translating a calculation expression (e.g., a supplier field of a purchase order, a default tax rate field of a supplier, as shown in fig. 3, and an accounting dimension field, as shown in fig. 6), may be understood as business object data that can be directly accessed or directly referenced through a translator of a platform; the function reference field usually refers to a field name (such as the encoding of the accounting dimension, the name of the accounting dimension, and the type of the accounting dimension shown in fig. 6) that the service function needs to acquire according to the service logic, which may be understood as service object data that the platform cannot directly acquire and needs to indirectly acquire through the service function; the most clear difference between the two fields is that the indirect reference field (i.e. function reference field) cannot be directly translated and is shown in the expression translation area, and the direct reference field (i.e. expression reference field) can be directly translated and is shown in the expression translation area.
Referring to fig. 1 to 4, a first aspect of the present application provides an embodiment of a dynamic field printing method, including:
101. a computational expression and a field identifier are configured.
The computational expression in the embodiment of the present application may be understood as a logical expression composed of one or more of numbers, operators, fields, number grouping symbols, free variables, and constraint variables, and a meaningful arrangement method capable of obtaining a final result, where the fields and functions used in the logical expression are usually derived from a function library of a dynamic business domain model (the business domain model may also be referred to as a business document model, and a common cost reimbursement order model and a common purchase order model).
Illustratively, the design process of the printing template may specifically include: custom configuring a computational expression of a target business object (e.g., a vendor) through an expression editor interface of a print template as shown in FIG. 3; and, a field identifier (for example, a bill Type Custom packet Type) for binding the computational expression is configured in a self-defined manner through a field identifier configuration interface of the printing template shown in fig. 2, so that the printing template finally determines the printing display data to which the computational expression refers by binding the field identifier, thereby realizing the printing display requirement shown in fig. 4 (the output result of the bill Type column is "value added tax").
102. An expression reference field and a function reference field are obtained.
In one specific implementation, the business domain model may be modeled as "model-element-attribute" such that each element supports different business characteristics, e.g., a material field (element layer, e.g., as a supplier of one of the basic data fields) under the purchase order model (model layer) supports obtaining its code field, name field, and associated carrying field (attribute layer); and the configuration of the computational expression may be used with the expression reference field and the function reference field to correspond to the associated business domain model data (e.g., the vendor field and its attributes, encoding).
Therefore, in order to output data on the document or the account table as a corresponding required calculation result according to the calculation logic of the calculation expression, that is, to display the data on the document or the account table by printing in a targeted manner, an expression reference field and a function reference field which are correspondingly used in the calculation expression need to be acquired first.
103. A dynamic print field is calculated.
Because the calculation expression in the embodiment of the application is a dynamic operation formula configured by a user (the dynamic state here can be understood as that which fields are displayed during printing, and a user other than a developer also has a setting authority), and is used for intervening in which data is displayed during printing through the operation logic contained in the calculation expression, the expression reference field and the function reference field can be calculated into a dynamic printing field representing the printing requirement of the user according to the operation logic contained in the calculation expression.
104. The result of the calculation of the dynamic print field is matched to the field identifier.
In practical applications, the calculation result of the dynamic printing field (referred to as the dynamic printing field result) may be understood as that data meeting the printing requirement of the user after logic calculation is output, so that the calculation result of the dynamic printing field is matched with the field identifier, and the calculation result is output as printing data to the output control of the printing template through the field identifier and then displayed on the printing preview interface.
According to the dynamic field printing method, the expression reference field and the function reference field can be calculated into the dynamic printing field through the self-defined calculation expression, so that the printing data required by the user is output to the printing template through the binding of the field identifier. Therefore, the method of the embodiment of the application can meet personalized printing display requirements of different users, can effectively reduce data redundancy and development workload compared with a traditional printing data adjustment scheme, and can effectively improve user experience by using the calculation expression which is ready to use.
Referring to fig. 2 to 8, the present application provides another embodiment of a dynamic field printing method, including:
501. a computational expression and a field identifier are configured.
502. And generating a printing task of the target business object.
When a user initiates a printing request to a certain document, a printing task related to a target business object needs to be generated according to the specified document and a designed printing template, so as to drive and execute subsequent operations of acquiring an expression reference field, a function reference field and the like. The designed printing template may include preset printing fields (such as document number and purchase date shown in fig. 4).
503. Acquiring all service field model information and function library information associated with a target service object;
because the contents of fields and the like correspondingly used in the calculation expression are usually from a business document model and a function library, and the data of one document in an enterprise application system is very much, if all the data in one document is directly selected for access before printing and outputting, the performance loss is not small; therefore, it is necessary to obtain all the service domain model information and function library information associated with the target service object, rather than all the massive information associated with each service object in the document, in a targeted manner by analyzing the calculation expression, so as to reduce performance loss and system operation cost.
504. An expression reference field and a function reference field are obtained.
And in all the acquired business field model information and function library information related to the target business object, the business field model data corresponding to the expression reference field and the function reference field is pertinently extracted, but the information corresponding to the field irrelevant to the printing requirement is not extracted, so that the loss of the system such as the operation time length is reduced.
505. A dynamic print field is calculated.
In the actual application process, the operating environment created by the enterprise application system should support all functions dynamically compiled by operating scripting languages such as Python or JavaScript, so that the scripting languages are used for self-defining the computational expressions, and more rich and robust computational characteristic scenes can be realized, instead of only supporting a general computational scene defined inside the platform as in the prior art (that is, if no scripting logic function required by a user is provided inside the platform, a corresponding required expression printing result cannot be realized through the platform); in the embodiment of the present application, an Iron Python is used to create an operating environment to support the operation of all functions dynamically compiled by a Python scripting language, and the operating environment may specifically include:
1) support general operations such as calculating the sum, converting the display and judging whether, for example: if the user does not want to print out the total amount in the displayed order (relating to a gift), the total amount may instead be displayed as: 0 x the number of gifts + the unit price of the non-gifts x the number of non-gifts.
2) And the dynamic printing field of the business field model data corresponding to the expression reference field and the function reference field is accessed in multiple stages by supporting the calculation of the expression reference field and the function reference field according to the operation logic of the calculation expression. Illustratively, the result of a single level access may be as shown in FIG. 4, with only one level fields printed and displayed: "value-added tax" (which is a lower expansion field belonging to the supplier field layer shown in fig. 3); the printing result of the multi-level access may specifically be that two levels of fields are displayed: "supplier. default tax rate", or, display three levels of fields: "supplier default tax rate code".
3) And the dynamic printing field for formatting and processing the business field model data corresponding to the expression reference field and the function reference field is calculated by supporting the operation logic for calculating the expression. Exemplarily, when the business domain model is a charge reimbursement form model and the business object is a certificate:
3.1, if the printing requirement of the client is the different accounting dimension of the line feed printout, the configuration of the calculation expression can be as shown in FIG. 6. It should be noted that, an elastic domain field formatting function FlexFormat (flexKey, format string, parser) is correspondingly used, which is a domain model function; the flexKey represents an elastic domain field identification or an elastic domain subfield identification; FormatString represents the formatting display rule of a single dimension, and the placeholders of the formatting display rule in FIG. 6 are: type — accounting dimension (e.g., asset class, expense item); coding the Code; type Name (house and building, material cost); the separator indicates a separator between the dimension values, and may be a line break "\ r".
Thus, according to the computational expression shown in FIG. 6, the computed result of the dynamic print field is shown in the third column of FIG. 8.
3.2, if the printing requirement of the client is to filter out the accounting dimension field of 'expense item', the configuration of the calculation expression can be as shown in FIG. 7. It should be noted that "/". join (filter (lambdax: (x.find ('expense item') <0), flexform ('FDetailID', 'Type: Code, Name', '/') [0]. GetString (2052). split ('/'))) is a clause in else, where:
(a) and a field formatting function FlexFormat, and the following checking dimension formatting results are used as follows:
"type 1: code 1, name 1/type 2: code 2, name 2/type 3: code 3, name 3 ".
(b) Splitting the function split, which may be specifically a function compiled by python language, to split the formatted value of the accounting dimension at (a) according to different accounting dimensions as boundaries, so as to obtain the following result:
"{ { type 1: code 1, name 1, { type 2: code 2, name 2}, { type 3: code 3, name 3} } ".
(c) The filter function (x: (x.find () <0), array), which may be specifically a function compiled in python language, is used to determine the type according to each calculated dimension value, for example, if the second string (the content in each "{ }" is a string) contains the name of the required filtering type, then type 2 is considered as the type to be filtered, and accordingly the following set can be obtained:
"{ { type 1: code 1, name 1, { type 3: code 3, name 3} } ".
(d) And (c) a splicing function join (array), which may be specifically a function compiled in python language, for splicing the set result obtained in (c) to display and output a string result as follows:
"type 1: code 1, name 1/type 3: code 3, name 3 ".
Thus, according to the computational expression shown in FIG. 7, the computed result of the dynamic print field is shown in the fourth column of FIG. 8.
506. The result of the calculation of the dynamic print field is matched to the field identifier.
The result of the calculation of the dynamic print field may specifically be the final result as explained in the above 3.1 or 3.2.
507. And outputting the printing data to the printing template.
And correspondingly outputting the preset printing fields and the calculation results configured in the printing template to a control of the printing template as printing data so as to obtain a self-defined printing display interface.
Step 501 is similar to step 101, and steps 504 to 506 are similar to steps 102 to 104, which are not described again.
Referring to fig. 9, a second aspect of the present application provides an embodiment of a dynamic field printing system, comprising:
