Question

i'm working with a flask to make a dashborard, in my project i have a script inside the flask app that generates the html code. and my question is how to use url_for to create the dynamic routing is this case, here is my code:

rec+='<td><a href="url_for(case,id='+row['ID']+'" id="'+str(row['ID'])+'" >More</a></td>'

Any ideas how to make it work and thank you in advance.

Answer 1

You should use {{ }} enclose the url_for statement.

rec += '<td><a href="{{ url_for(case, id=' + str(row['ID']) + ') }}">More</a></td>'

or use format string(more readable):

rec += '<td><a href="{{ url_for(case, id={}) }}">More</a></td>'.format(row['ID'])
