i want prevent it, how can i solve this problem?

Hello everyone, since django-googlesearch is not working anymore on django 1.8, does anyone know how can I implement google custom search to my django website?

hi

What is a form Field.prepare_value supposed to return?

this is not documented: https://github.com/django/django/blob/master/dj...

I subclassed TypedMultipleChoiceField, but get TypeError 'int' object is not iterable, the error seems to come from that prepare_value method

`if type(value) is not list: value = []; return value` seems to solve my issue

pytony: Field.clean() is supposed to handle that (in this case, it delegates to ._coerce(), which looks for empty values, and returns a list if this is one).

schinckel: thanks, then I should rather do the conversion in _coerce

Can someone tell me how can I handle my haystack template? Example only shows "{{ result.object.title }}" as a result but i have models without "title" field in it

No, you shouldn't touch _coerce.

pytony: If all you need to do is coerce values, then you shouldn't need to subclass, just pass in a coerce() function.

use the coerce attribute the, I guess

(to the field definition)

Yep.

ok

thank you

field_name = forms.TypedMultipleChoiceField(coerce=float)

for instance.

how to prevent duplicate form submits in django?

same way as everything else?

use javascript?

disable the button using JS? have a version/sequence/nonce on the form?

in my case I think I have to do coerce=(lambda x: x if type(x) is list else [])

especially, 0 should be treated as []

pytony: why not just "x if x else []" ?

at least use isinstance(x, list) instead of type

ah yeah much better x)

Can someone tell me how can I handle my haystack template? Example only shows "{{ result.object.title }}" as a result but i have models without "title" field in it, how people usually manage to make single search page for whole models?
