is there any reason not to just use filter() then all()

is 1000 lines in an template a lot?

it it mainly html?

what is the best payment processing package for django?

I'm trying to move to an SQL database, but because this was my first application and has squillions of db changes I deleted all the migration and cache folder so it would skip all the conflicts from all the changes I did.

Now when I run my initial migrate I get this: "Applying admin.0001_initial...Traceback (most recent call last):"

"_mysql_exceptions.OperationalError: (1005, 'Can\'t create table `leaderboard`.`#sql-37_32` (errno: 150 "Foreign key constraint is incorrectly formed")')"

I can't find admin.0001, guessing it is from the internal admin system.

Any suggestions?

I made all migrations individually and then did a migrate and it worked.

anyway to only allow updating/creating in drf to superusers

AlwaysHigh: nope, not mainly html.

mainly tags

ie django template tags

well if its not affecting the reponse time doesnt sound like an issue

1000 lines mainly tags? How does that work?

Are we talking about template syntax aka {{% or tags like var|tag1|tag2

Does a DateTimeField use a different format on MySQL to SQLite?

Inserts keep failing with invalid format and I can't see why.

gcain: code + traceback

Does the "1970-01-01 00:00 UTC" part imply that the value the db is getting is a null or 0?

This is what gets printed out in debug "Valid form 2018-09-08 15:00:00 "

wait... are you not using a ModelForm?

[also, where's the form declaration??]

FunkyBob: Form declaration included now http://dpaste.com/1AKBNQ8

Sorry, was trying to keep the noise down.

I'm using forms.Form?

ok... now... _why_ aren't you using a ModelForm ?

is it just you don't know them?

Maybe because I don't know about them.

This is my first app. :)

ok

so with a Modelform, it takes all you told django about your model, and makes a form to suit

ALSO... it gives the form a save() method that updates and saves a model instance

so MOST of the [tedious] work you've done here, wouldn't be needed

Like creating the actul form?

also... don't specify name attributes for widgets

Does it do it itself?

yes

let's face it... django would be failing the "protect you from the tedious things" metric if it didn't

Oh, it does too.

Ahhh no. This is what I wanted.

and if you customised the widgets just to add the form-control attr... there's probably an easier way

You have no idea how many forms I have. haha.

like iterating self.fields in an overridden __init__

Thanks, I'll go update this and report back.

as for custom widget rendering... django forms now support templates for doing that

How do I get the post data back into the ModelForm?

Just form = EventAddForm(request.POST) then form.save()?

Is this right? date = models.DateTimeField(default=datetime.date.today)

:)

yes, it really can be that simple :)

I get the identicle validation error on save()

this is why generic views are possible

Yeh, crazy how simple it can get with Django.

so, can you show current updated code, and the error?

also, if you can, the posted data

are you trying to create a new Event? if so, why are you pulling one from the DB in get()?

Yes.

The set_event is the current event that has been set as active. I pull it because it generates the menu in the template.

However, this is the very first run.

a bare "except:" is considered very poor form.. you should catch only the exceptions you know how to handle

Yes, I'm aware of that now.

ok... I'm going to rewrite this as a plain view function so you can see the reasoning a little more clearly

I was trying to do a catch(e){ console.log(` you can an error ${e}`); } type thing.

Thanks.

So much tidier!

not quite right, though... given what I know now about your existing event idea

is that something you usein the template?

The set_event? Yes.

It always has to be sent back with every call, even if empty.

I couldn't work out how else to do it.

So I don't need to instatiate the event, because event_config /is/ the event.

"sent back"?

Og, now I see how except works.

wait... _is_ theevent? so this is a create-or-update view?

This is purely for the template view.

what does redirect(event) do?

Does that send it back to the form, but populated?

redirect is a handy shortcut that wraps many ideas

if you pass it a model instance, and t hat instance has get_absolute_url() method... it will call that to get where to redirect to

Should add_event be a class or a method?

or you can pass it a string [and args/kwargs] to use for a redirect() lookup

ok.

oops... it should be a function

Cool, makes more sense.

Oh, you did both post and get in a single function.

Your function returns a 405, method not implemented.

is it from the URLs.py config?

Working again!
