Description

Dynamic form generation method and device

Technical Field

The invention relates to the technical field of Web front-end application (WebApp) design, in particular to a dynamic form generation method and a dynamic form generation device.

Background

The HTML form is a main component of the Web application program, and the basic principle of the HTML form is that the form required by the Web application program for providing specific scene services is formed by specific combination of different types of form elements (such as input boxes, check boxes, radio buttons, submit buttons and the like), and input data of a user is collected through interaction with the user. After the HTML form collects user input data, the form data is often selected to be persisted in the data for subsequent application. Among conventional Web applications, due to the advantages of relational databases (e.g., SQL Server, Oracle, MySQL, etc.) in terms of structured query, transactional and consistency, even today with rapid development of internet technologies, many large internet projects will introduce NoSQL databases (e.g., Mongodb, Redis, Riak, Membase, Neo4j, HBase, etc.) into their data architectures, but SQL databases are still selected as the first choice for form data persistence, and NoSQL databases are more used for persistent storage and caching of massive data, unstructured data, and data with high requirements on data access speed.

With the popularization of software development engineering ideas, Web application programs applied in some enterprise-level business scenes (such as business process management, office automation and enterprise resource planning) gradually get rid of a pure mode of manually customizing and developing HTML forms, and online and dynamic development of the HTML forms is realized by selectively developing and providing a form engine. However, when the HTML form selects the SQL database to perform persistent data operation, once the HTML form needs to be dynamically modified (such as increasing or decreasing table elements), the persistent data operation of the corresponding SQL database and the Web application program must be modified in the database table (schema) and the code layer, and the modification of the database table will bring hidden troubles to the stability of the database and the security of the data, and the modification of the code of the persistent data of the Web application program also requires the Web application program to be restarted to be effective, which affects user experience. In particular, for a cloud computing Web application in the SaaS (software as a service) form, the above operation cannot occur at all in no operation on a program line.

Example one

Taking a form as an example, the form design function is mainly to input the annual course scores of students. Before designing a form, modeling objects participating in the form, and establishing a user object model and a achievement object model: the student object model comprises attributes such as 'name', 'age' and the like; the achievement object model mainly comprises: the attributes of "course" and "achievement".

The name is Zhang III,

the age is 18 percent,

"achievement list" [ { "course": Chinese "," achievement ": a" }, { "course": math "," achievement ":

"B"}],

1553226681 is used as a time stamp.

Where the time stamp records the time at which the data was generated.

The student object instance after the form data instance is split and converted is

"ID":"X001",

The name is Zhang III,

the age is 18 percent,

1553226681 is used as a time stamp.

An example of an achievement list object is

"student" "X001",

"achievement list" [ { "course": Chinese "," achievement ": a" }, { "course": math "," achievement ": B" } ],

1553226681 is used as a time stamp.

At the moment, the object model and the 'input student score' form are dynamically modified, and the attribute support of the 'gender' of the students and the attribute support of the 'teaching teacher' in the score are added after modification. And inputting data of a new student (such as Liqu), wherein after the form is submitted, the generated form data example is as follows:

{ "name": lie four ",

the age is 17 percent of the total age of the patient,

"gender" means "female",

"achievement list" [ { "course": Chinese "," achievement ": a", "teaching teacher": Mary "}, {" course ": mathematics", "achievement": a "," teaching teacher ": John" },

"timestamp" 1553226681 }.

The student object instance after the form data instance is split and converted is

{"ID":"X002",

The name is Lifours,

the age is 14, and the number of the children is 14,

"gender" means "female",

"timestamp" 1553226681 }.

An example of an achievement list object is

{ "student": X002",

"achievement list" [ { "course": Chinese "," achievement ": a", "teaching teacher": Mary "}, {" course ": mathematics", "achievement": a "," teaching teacher ": John" },

"timestamp" 1553226681 }.

When the form data is updated, if the Chinese score of the student 'LiSi' is updated to be B, the method converts the update request into a new request and keeps the reference of the original data in the new data.

{ "student": X002",

"achievement list": Chinese { "course": Chinese, "" achievement ": B," "lecture teacher": Mary "}, {" course ": mathematics," "achievement": a, "" lecture teacher ": John" },

a "time stamp" of 1553745899 that is,

"request" "update",

"previous version data ID": 2f791a10dbcda7a7a490a1ec10981f44 "}.

The key "last version data ID" records the source data of the update object, and the corresponding value is the unique value obtained by hashing (such as MD5) the last version data object. Similarly, the "delete" request for data can be converted into the "add" request.

It can be seen from the above cases that when the form changes dynamically, the collected information in the object data instance also changes correspondingly, but because the persistence layer and the data layer do not need to be modified in terms of codes and a database, the new addition, update, query, analysis and statistics of the mobile phone data before and after modification can be supported, and therefore the change of the dynamic form does not need to require the SaaS system to be restarted.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.

the generating module is used for generating a form page according to the object model library; generating a corresponding dynamic form according to the form page, wherein the form page is adopted to receive a user instruction, and the instruction comprises at least one of a data adding request, a data updating request, a data deleting request, a data inquiring request and a data analyzing request; and generating a corresponding dynamic form according to the instruction, wherein,

the step of generating the dynamic form by the form page receiving the instruction of the request for adding, updating and deleting data includes: receiving requests for adding, updating and deleting data by adopting the form page; converting the data updating request and the data deleting request into data adding requests, wherein references to original data are reserved in data of the data adding requests; generating a form data instance according to the data increasing request; converting the form data instance into one or more object data instances; generating a dynamic form according to the object data instance;

the step of the form page receiving the instruction of the query data request to generate a dynamic form includes: receiving a data query request by adopting the form page; the form page is used for acquiring a query result from a big data warehouse according to the query data request; generating a dynamic form by adopting a query result;

the step of the form page receiving the instruction of the analysis data request to generate a dynamic form includes: receiving a data analysis request by adopting the form page; the form page is used for acquiring an analysis result from a big data warehouse according to the analysis data request; and generating a dynamic form according to the analysis result.
