Data from form is not being saved in DB

[Герман Свердлов]

Hi all!

I'm newbie in Django, still trying to figure out how everything works and this is my first back end framework, that I'm using. Currently building an app like booking.com but for commercial property.

Among others I have models that represent office centers and office spaces this is one-to-many relationship (1 office, many spaces). I've made a form that adds spaces to a particular office, but this form doesn't seem to save data.

I'm stuck on the following:

- Am I right that I need to point an action attribute in the form to specify view which will save form data into DB? If yes, I'm struggling how to do that, because I'm getting errors ReverseMatch

- If this is not about action attr, what am I missing?

Thank you in advance

German

Hello,

Answer to your first question: You don't have to explicitly mention action attr. without that too it is possible to achieve the same operation.

you can check "practice04" in this Repository :  

For reverse match error:

specifying app_name under urls.py file helps to debug such errors.

Please post the full error including the traceback and any additional information.

To use name urls, you should use this format

app_name:name

Where name is the name your assigned to the path while defining urls
