How to choose submit button name using element id in MechanicalSoup?

Question

I need to simulate the submit action on a form that has 2 options for submit button with both the options having the same name attribute. Here's how they look using the Inspect tool:

So, they differ in their id and value attributes but not the name attribute.

The problem I am having is that the submit_selected() method in MechanicalSoup only accepts Button Name as the parameter:

submit_selected(btnName=None, *args, **kwargs)

So how can I use this method to uniquely select the appropriate button?

Answer 1

If I'm not mistaken, you can use other attributes. For instance, we can use id or value from your example as they are not identical. like so....

by id

my_button = br.get_current_page().find('input', id='edit-save')

br.submit_selected(btnName=my_button)

by value

my_button = br.get_current_page().find('input', value='Search')

br.submit_selected(btnName=my_button)

Answer 2

Use Form.choose_submit. This function can receive a BeautifulSoup Tag element, so you can use whatever BeautifulSoup provides to select the right submit button.
