Currently working with the web2py framework, I am faced with a challenge in creating a SQLFORM without a submit button. The issue arises from having multiple forms on the page, some of which share common fields, making it impossible to use SQLFORM.factory(). My goal is to have only one form equipped with a submit button that can effectively handle data input from all other forms present. Any recommendations or insights on the most efficient approach to achieving this?
form1 = SQLFORM(db.table1, buttons=[])
By implementing this code snippet, form one will be displayed without any buttons, including the submit button.
One possible approach is to assign the same value to the _formkey and _formname fields for all forms. Here's an example:
my_form2.formname = my_form1.formname
my_form2.formkey = my_form1.formkey
To manually hide submit buttons, you can try this method:
my_form1.element('input', _type = 'submit')['_style'] = 'display:none'
Keep one submit button with matching formname and formkey values as a way to submit the forms.
When inserting variables into database tables, consider using the following syntax:
db.table1.insert(**db.table1._filter_fields(request.vars))
db.table2.insert(**db.table2._filter_fields(request.vars))
If fields share the same names, there could be potential issues, so exercise caution.
If you're looking to streamline your forms, you can combine multiple SQLFORMs by appending one form to another. This way, you'll have a single "multiple form" with only one submit button. Here's an example of how you can achieve this in your controller:
form1 = SQLFORM(db.table1)
form2 = SQLFORM(db.table2)
form1.append(form2)
if form1.process().accepted:
#apply filters to the fields from each form and perform desired actions
response.flash = 'OK'
elif form1.errors:
response.flash = 'NOT OK'
return dict(form=form1)
Notice that I interacted solely with form1 in the code above. This is because it serves as the main form and enables you to handle filtering efficiently across all your forms. Hopefully, this explanation proves useful.
