'I've a problem with django update in crud?
I have a problem where, in the update part when the form is displayed, in whichever fields there is more than one word (like name, address) the first one is only displayed in the form to be edited, the rest is gone. I went through the whole project multiple times but I can't find the solution. Please help me. Thanks in Advance!!!
