WEB development framework series (3) page function development (2), Framework page Function

As described in the previous section, the development of basic data currency information is complete only by using auxiliary development tools, creating data tables, and entering the table name.

At last, we also mentioned that we may also be faced with maintenance of some other basic information, but it is not as simple as only code and name, and there may be other data items.

For example, assume that an exchange rate field is also required in the currency table BASE_CURRENCY.

First, we adjust the table, add the RATE field, and modify the description of all columns in the table. For example, the description of UPDATE_USER is "modifier"

You can adjust the description of the field column here, which means that you have adjusted the Label description on the page.

Next: open our program design function

Go to the program design list page, where you can query all the configuration-based images.

OK. Click Add to create the required Currency information screen.

Click Refresh to display all the imported fields.

Next, click the quick maintenance button to configure fields quickly.
