Django Internal server error - widget_tweaks failed to parse render_field

[jeffm89]

Afternoon this is my first time positing an issue so please bare with me.

I've cloned the repo to my local machine. When I run the django server, I get the landing page "index.html" but when I try to open one of the modals, I get the bellow TypeError: cannot pickle. I then tried to run the tests but 3 of them fail for the same TypeError: cannot pickle.

I thought it could be related to a difference in local python version. So I used the contained docker-compose, but ran into the same error.

Thanks

Jeff

Hi,

I've been digging a little this afternoon and found the issue to come from the widget_tweaks lib.

By removing the widget_tweaks tag {% render_field field class="form-control" placeholder=field.label %} with the standard django {{field}} it is able to render it ok.

Example in create_book.html

Further to that I've found a change in the widget_tweaks change log. After updating to newest version 1.4.12 the index page works, can add books now.

The tests that were failing on the initial TypeError are now passing.
