Detailed Description
In the conventional technology, the following two print data adjustment schemes are often adopted to meet different print display requirements of a client under the same set of service data:
<1>, print plug-in intervention protocol: business developers adjust print data by developing print plugins supported by enterprise application systems targeted. <2>, print data readjustment scheme: using a third party tool to perform simple calculation adjustment on the data displayed during printing; if the enterprise application system binds the fields under the data field model through the Excel template, a print Excel file is generated, wherein the Excel template can readjust the print data by utilizing the library function of the Excel.
The two schemes can meet different printing display requirements of clients under the same set of business data, but have defects for enterprise application systems:
<1>, print plug-in intervention protocol: the business scene of the enterprise application system is complex, and the printing scene is also the same, when each bill needs to be interfered by a printing plug-in, a developer is required to consume a large amount of labor cost to carry out corresponding matching adjustment. <2>, print data readjustment scheme: because of the complex bill data, part of business logic cannot intervene deeply, for example, a third party tool Excel has difficulty in filtering out certain printed fields.
In the embodiment of the present application, a dynamic field is understood to be a virtual field dynamically calculated during adjustment of print data, and has two kinds of information, namely a calculation expression and a field identifier (hereinafter or referred to as dynamic field identifier). The expression reference field, commonly referred to as a field name (such as a vendor field of a purchase order, a default tax rate field of a vendor, and an accounting dimension field shown in fig. 6) that can be directly obtained by translating a computing expression, can be understood as business object data that can be directly accessed or directly referenced by a translator of the platform; the function reference field refers to a field name (such as the coding of the accounting dimension, the name of the accounting dimension and the type of the accounting dimension shown in fig. 6) which is required to be obtained by the business function according to the business logic, and can be understood as business object data which cannot be directly obtained by the platform and is required to be indirectly obtained by the business function; the most clear difference between the two fields is that indirect reference fields (i.e., function reference fields) cannot be directly translated and shown in the expression translation region, whereas direct reference fields (i.e., expression reference fields) can be directly translated and shown in the expression translation region.
Referring to fig. 1 to 4, a first aspect of the present application provides an embodiment of a dynamic field printing method, including:
101. the computing expression and field identifier are configured.
The calculation expression in the embodiment of the present application may be understood as a logic expression composed of one or more of numbers, operators, fields, digital grouping symbols, free variables and constraint variables, so as to obtain a meaningful arrangement method of the final result, where the used fields and functions are often derived from a function library of a dynamic service domain model (the service domain model may also be referred to as a service bill model, a common expense reimbursement bill model and a purchase order model).
Illustratively, the design process of the print template may specifically include: custom configuring a computational expression of a target business object (e.g., vendor) through an expression editor interface of a print template as shown in fig. 3; and, by the field identifier configuration interface of the print template as shown in fig. 2, the field identifier (e.g., ticket type Custom Ticket Type) for binding the calculation expression is configured in a customized manner, so that the print template finally determines the print display data pointed to by the calculation expression by binding the field identifier, thereby realizing the print display requirement as shown in fig. 4 (the output result of the ticket type column is "value added tax").
102. An expression reference field and a function reference field are obtained.
In one specific implementation, the modeling manner of the business domain model may be "model-element-attribute" such that each element supports different business characteristics, for example, a material field (element layer, for example, a provider as one of the basic material fields) under the purchase order model (model layer), and supports acquiring its coding field, name field, and associated carrying field (attribute layer); and the configuration of the computational expression may use an expression reference field and a function reference field to correspond to the associated business domain model data (e.g., vendor field and its attributes, encodings).
Therefore, in order to output the data on the bill or the account table in the form of the corresponding required calculation result according to the calculation logic of the calculation expression, the data on the bill or the account table can be displayed by the printing to be targeted, and the expression reference field and the function reference field which are correspondingly used in the calculation expression need to be acquired first.
103. A dynamic print field is calculated.
Since the calculation expression in the embodiment of the present application is a dynamic operation expression configured by the user (the dynamic state can be understood as which fields are displayed during printing, and the user outside the developer also has a set 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 according to the operation logic contained in the calculation expression, so that the dynamic printing field representing the printing requirement of the user can be calculated.
104. The calculation result of the dynamic printing field is matched to the field identifier.
In practical applications, the calculation result of the dynamic printing field (herein or referred to as the dynamic printing field result) can be understood as data that meets the printing requirement of the user after being logically calculated, so that the calculation result of the dynamic printing field can be output to the output control of the printing template as printing data through the field identifier by matching the calculation result of the dynamic printing field with 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 printing data required by a user is output to a printing template through binding of the field identifier. Therefore, the method of the embodiment of the application not only can meet the personalized printing display requirements of different users, but also can effectively reduce the data redundancy and the development workload compared with the traditional printing data adjustment scheme, and the computing expression which is matched and used in the middle can effectively improve the user experience.
Referring to fig. 2 to 8, another embodiment of a dynamic field printing method is provided, including:
501. the computing expression and field identifier are configured.
502. A print job for the target business object is generated.
When a user initiates a print request to a certain bill, a print task related to a target business object is generated according to the designated bill and the designed print template, so as to drive and execute operations such as a follow-up acquired expression reference field, a function reference field and the like. The designed printing template may include preset printing fields (e.g., document number and purchase date as shown in fig. 4).
503. Acquiring all service domain model information and function library information associated with a target service object;
because the contents such as the fields and the like correspondingly used in the calculation expression are often derived from a business bill model and a function library, the data of one bill in the enterprise application system are very much, and if all the data in one bill are directly selected for access before printing and outputting, no small performance loss exists; therefore, all the business domain model information and function library information associated with the target business object are acquired in a targeted manner through analyzing the calculation expression, but not all the massive information associated with each business object in the bill, so that the performance loss and the system operation cost are reduced.
504. An expression reference field and a function reference field are obtained.
And extracting the service domain model data corresponding to the relation between the expression reference field and the function reference field instead of the information corresponding to the field of irrelevant printing requirements in the acquired all service domain model information and function library information related to the target service object in a targeted way so as to reduce the loss of system operation time and the like.
505. A dynamic print field is calculated.
In the actual application process, the running environment created by the enterprise application system can support all functions dynamically compiled by script languages such as operation Python or JavaScript, so that a user-defined calculation expression of the script language can be utilized to realize a richer and more robust calculation characteristic scene, rather than supporting only a general calculation scene defined in the platform as in the prior art (namely, if a script logic function required by a user is not provided in the platform, a corresponding required expression printing result cannot be realized through the platform); the embodiment of the application uses the photon Python to create an operation environment to support all functions dynamically compiled by the operation Python scripting language, and the operation environment specifically can include:
1) General operations such as calculating a sum, converting a display, and judging whether the display is non-judgment are supported, for example: if the user does not want to print the total amount in the display order (related to the gift), the total amount may instead be displayed as: 0 x number of gifts + unit price of non-gift x number of non-gifts.
2) And supporting calculation logic according to the calculation expression, and calculating the expression reference field and the function reference field into dynamic printing fields for accessing the business field model data corresponding to the expression reference field and the function reference field in multiple stages. Illustratively, the results of the single level access may be as shown in FIG. 4, with only one level of fields printed and displayed therein: "value-added tax" (which is a lower expanded field attributed to the provider field layer shown in fig. 3); the printing result of the multi-stage access may specifically be that two stages of fields are displayed: "vendor. Default tax rate", or, display three-level field: "vendor. Default tax rate. Code".
3) And supporting calculation logic according to the calculation expression, calculating the expression reference field and the function reference field into dynamic printing fields for formatting business field model data corresponding to and associated with the expression reference field and the function reference field. Illustratively, when the business domain model is a fee reimbursement bill model and the business object is a credential:
3.1 if the customer's print requirements are different accounting dimensions for the linefeed printout, the configuration of the computational expression may be as shown in FIG. 6. It should be noted that, an elastic domain field formatting function FlexFormat (flexKey, format string, separator) is correspondingly used, which is a domain model function; flexKey represents an elastic domain field identification or an elastic domain subfield identification; formatting string represents a single dimension formatting display rule, and the placeholder words of the formatting display rule in fig. 6 are: type-accounting dimension (e.g., asset class, cost item); encoding a Code; name of type Name (house, building, material cost); the separator represents a separator between the dimension values, which may be a line feed symbol "\r".
Thus, according to the calculation expression shown in fig. 6, the calculated dynamic print field result is shown in the third column of fig. 8.
3.2 if the customer's print requirement is to filter out the accounting dimension field of "expense item", the configuration of the computational expression may be as shown in FIG. 7. It should be noted that "/", join (filter (x.find (' expense item ') < 0), flexFormat (' FDetailID ', ' Type: code, name ', ' v) [0]. GetString (2052). Split ('/')))) is a clause within else, wherein:
(a) The field formatting function FlexFormat uses the following accounting dimensions to format the result as follows:
"type 1: code 1, name 1/type 2: code 2, name 2/type 3: code 3, name 3).
(b) A split function split, which may specifically be a python language compiled function, splits the accounting dimension formatted value at (a) according to different accounting dimensions as boundaries 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 filter (x (x.find () < 0), array, which may be specifically a python language compiled function, is used to determine the type according to each accounting dimension value, for example, if the second string (the content in each "{ }" is a string) includes the name of the required filtering type, then the type 2 is considered as the type that needs to be filtered, and the following set is obtained correspondingly:
"{ type 1: code 1, name 1}, { type 3: code 3, name 3 }).
(d) A concatenation function join (array), which may be specifically a function compiled in the python language, for concatenating the aggregate results obtained at (c) to display a string result that outputs:
"type 1: code 1, name 1/type 3: code 3, name 3).
Thus, according to the calculation expression shown in fig. 7, the calculated dynamic print field result is shown in the fourth column of fig. 8.
506. The calculation result of the dynamic printing field is matched to the field identifier.
The calculation result of the dynamic print field may be specifically the final result as described in 3.1 or 3.2 above.
507. The print data is output to a print template.
And correspondingly outputting the preset printing fields and the calculation result configured in the printing template to a control of the printing template as printing data to obtain a self-defined printing display interface.
Step 501 is similar to step 101, steps 504 to 506 are similar to steps 102 to 104, and detailed description thereof will be omitted.
