Re: Problem hiding fields from admin page based on another fields value

[Hilde Rafaelsen]

I get same error as before; 'NoneType' object has no attribute 'readiness' 
when I changed to your excample. I don't understand why this is not working 
for me, but for everyone else

Is it something I have forgot to import? I hope you can take a quick look 
at my uploaded files. Is it ok to just use get_form from the admin class 
directly, or do I need to create a Form class as well?

  Hi,

  

 Thanks for the response.

  

 What do you mean by tri-state?

  

 I changed my get_form to this:

 def get_form(self, request, obj=None, **kwargs):

form = super(RequestForChangeAdmin, 
 self).get_form(request, obj, **kwargs)

if obj:

if obj.readiness == 
 True:


 self.exclude = ("readinessDescription", )

form = 
 super(RequestForChangeAdmin, self).get_form(request, obj, **kwargs)

return form

  

 No my code run without errors, but nothing happpends though ☺

  

 I have tried to change the readiness filds to yes and no, but the field 
 readiness descriptions is always displayed. Maybe it is not possibly to 
 get 
 a fields attribute value from admin before the admin form is posted or 
 stored in database? Do you know?

  

 Regards,

 Hilde from Norway

Re: Problem hiding fields from admin page based on another fields value

[Timothy W. Cook]

try this get_form:

def get_form(self, request, obj=None, **kwargs):
if obj.readiness:
self.exclude = ("readinessDescription", )
return super(RequestForChangeAdmin, self).get_form(request, obj, **kwargs)


I have never used 'exclude' but it looks like yours should work.

 Hello,

 If you look at my model I want to hide the field readinessDescription
 if readiness value is False (no), when the user log into admin page.

 In model.py:
 class RequestForChange (models.Model):
  rfc = models.AutoField (primary_key=True, help_text="This is the grey
 text")
 heading = models.CharField("Heading", max_length=50)
readiness = models.NullBooleanField("Readiness", blank=True,
 null=True)
readinessDescription = models.TextField("Description of
 readiness", max_length=250, blank=True, null=True)


 I found some hints on the web about using get_form from my
 RequestForChangeAdmin page, but it won't work because i get this error
 'NoneType' object has no attribute 'readiness'


 Here is what I have in admin.py:

 class RequestForChangeAdmin(admin.ModelAdmin):
 formfield_overrides = {
  models.ManyToManyField: {'widget': CheckboxSelectMultiple},
 }
 list_display = ('rfc', 'heading', 'enviroment', 'status')
  search_fields = ('changeId',)

 if obj.readiness == True:
 self.exclude = ("readinessDescription", )
  form = super(RequestForChangeAdmin, self).get_form(request, obj,
 **kwargs)
 return form

I have uploaded my model and admin file and hope someone can tell me why I 
can't get my get_form method to work :)

Re: Problem hiding fields from admin page based on another fields value

Thanx,

I now changed my if test to just if obj.readines but then I get the error 
message 'NoneType' object has no attribute 'readiness'


I have tried with several fields from my model, but I always get this 
error. I guess it must be something essential I am doing wrong here, since 
my obj seems to be none always...

I have get_form inside my modelAdmin class.

Re: Problem hiding fields from admin page based on another fields value

[Timothy W. Cook]

Maybe it is not possibly to get a fields attribute value from admin before
the admin form is posted or stored in database? Do you know?

Yes, it is possible.  I use this to set which fields are readonly before
defining the fieldsets.  It works great.


def get_form(self, request, obj=None, **kwargs):
try:
if obj.published:
self.readonly_fields =
['prj_name','published','lang','schema_code','description','sem_attr','resource_uri','asserts',

'label','performer_p','function','mode','simple_function','simple_mode',]
except (AttributeError, TypeError) as e:
self.readonly_fields = ['published','schema_code']
return super(ParticipationAdmin, self).get_form(request, obj,
**kwargs)

Re: Problem hiding fields from admin page based on another fields value

[Timothy W. Cook]

What do you mean by tri-state?

You are using a field that allows three states: TRUE, FALSE and NULL.

If I understand the model, readiness would either be TRUE or FALSE.  But if
you do not want to change your field type to:
readiness = models.BooleanField("Readiness", blank=True)

then try changing:
if obj.readiness == True:

to:

if obj.readiness and obj.readiness == True:

or just:
if obj.readiness:

Will give you the same result.

This way if it doesn't exist it will not fail on the  '== TRUE' test.

Re: Problem hiding fields from admin page based on another fields value

[Hilde Rafaelsen]

Hi,

 

Thanks for the response.

 

What do you mean by tri-state?

 

I changed my get_form to this:

def get_form(self, request, obj=None, **kwargs):

   form = super(RequestForChangeAdmin, 
self).get_form(request, obj, **kwargs)

   if obj:

   if obj.readiness == True:

   self.exclude 
= ("readinessDescription", )

   form = 
super(RequestForChangeAdmin, self).get_form(request, obj, **kwargs)

   return form

 

No my code run without errors, but nothing happpends though ☺

 

I have tried to change the readiness filds to yes and no, but the field 
readiness descriptions is always displayed. Maybe it is not possibly to get 
a fields attribute value from admin before the admin form is posted or 
stored in database? Do you know?

 

Regards,

Hilde from Norway

Re: Problem hiding fields from admin page based on another fields value

[Timothy W. Cook]

Is 'readiness' really a tri-state flag?

Anyway you may want to test if obj.readiness exists, and is TRUE.

if obj.readiness and obj.readiness == TRUE:

Problem hiding fields from admin page based on another fields value

[Hilde Rafaelsen]

Hello,

In my django admin page I want to hide some filelds from users if a special 
field value is set. I have tried different solutions to solve my problem 
but is stucked and hope someone can help me,

If you look at my model I want to hide the field readinessDescription if 
readiness value is False (no), when the user log into admin page. 

In model.py:
class RequestForChange (models.Model):
rfc = models.AutoField (primary_key=True, help_text="This is the grey text")
heading = models.CharField("Heading", max_length=50)
   readiness = models.NullBooleanField("Readiness", blank=True, 
null=True)
   readinessDescription = models.TextField("Description of readiness", 
max_length=250, blank=True, null=True) 


I found some hints on the web about using get_form from my 
RequestForChangeAdmin page, but it won't work because i get this error 
'NoneType' object has no attribute 'readiness'


Here is what I have in admin.py:

class RequestForChangeAdmin(admin.ModelAdmin):
formfield_overrides = {
models.ManyToManyField: {'widget': CheckboxSelectMultiple},
}
list_display = ('rfc', 'heading', 'enviroment', 'status')
search_fields = ('changeId',)
list_filter = ('enviroment', 'acceptAT', 'status')
date_hierarchy = 'criticalDate'
inline = [RequestForChangeInline]
 def get_form(self, request, obj=None, **kwargs):
form = super(RequestForChangeAdmin, self).get_form(request, obj, **kwargs)
 print obj
if obj.readiness == True:
self.exclude = ("readinessDescription", )
form = super(RequestForChangeAdmin, self).get_form(request, obj, **kwargs)
return form

Yeah, clearly I followed the wrong tutorial as I was trying to learn  
things.  Ah, well, at least now I *have* learned something.

Thanks for the help, everyone.

You should fix those things, editable didn't work because 'False' with
quotes isn't a valid boolean value. The prepopulate is probably not
necessary, because all it does is include some javascript that fills
the field for you as you edit the other fields. Best just to overrride
the save method and populate the slug field with whatever data you need
before saving.

Re: hiding fields in admin

[Tamara D. Snyder]

I don't know.  My slug field looks like this:

slug = models.SlugField(
   'Slug',
   prepopulate_from=("title",),
   help_text='Automatically built from the title - do  
not fill in yourself.',
   primary_key='True',
   editable = 'False'
   )

but it definitely shows up in the admin.

Wait!  There it is:  editable='False'  if I make that editable =  
False (without the quotes) then it doesn't show up.  With the quotes  
it does show up, but it is not editable.

Re: hiding fields in admin

[Sean]

That's weird, because it hides it for me.
I have a field like this:
objects_path = models.CharField(maxlength=50, null=True, editable=False)

and it is clearly not visible in the admin.

Re: hiding fields in admin

[Tamara D. Snyder]

It just makes the field not editable.  Actually, it looks like you  
can edit the field - type in new stuff, etc. - but when you hit save,  
that field is not saved.  This is fine with me, because what I  
*really* wanted was to keep knuckleheads from changing the slug  
field.  I'd also like to hide it (to make it less tempting to the  
knuckleheads), so I'll try the javascript thing.  For some reason I  
was concentrating on just the hiding part and didn't even think of  
using "editable=false" until you mentioned it.

Re: hiding fields in admin

[Tamara D. Snyder]

Thank you, this works pretty well.

Actually, "editable=false" does not hide the field from the admin,  
but it will keep the field from being edited, and I can use the  
javascript trick to make it hidden, so all is well for me.

Thanks a lot, guys!

Re: hiding fields in admin

[Aidas Bendoraitis]

One more way would be to have a javascript function which changes
 to  for the slug field.
Something like this:

window.onload = function() {
document.getElementById("id_slug").type="hidden";
}

Good luck!

Re: hiding fields in admin

[Sean]

Maybe you would want the "editable=False" parameter in your model, which
hides the field from the admin. Then simply populate the field in the
save method.

  You can override the save() method and generate the slug yourself.
There's also a templatetag that 'slugfies' a string. I think you can
either use it to output the var or import the function on your save().

hiding fields in admin

[Tamara D. Snyder]

Hi all,

In my "Event" model I have a slug field that is automatically  
generated from another field.  I would like to hide the slug field  
from admin users, but still allow it to be automatically generated.   
I know I can hide it by using the "fields" parameter in the admin  
class of my model.  But if I do this then the slug field is not  
automatically generated when I create a new event.  Is there a way to  
hide the slug field, but still have it be filled in when I create a  
new event?

Thanks!

Tamara

Re: Hiding fields in admin interface

[pgross]

Thanks, that's really helpful.  I missed that argument when I was going
through the docs.

Ahh, that makes it much easier! You can put the foreign key in there
with the field argument "raw_id_admin=True". It will be much quicker to
load and much cleaner to use.

class Poll(meta.Model):
 huge = meta.ForeignKey(Huge, raw_id_admin=True)

 -rob

Re: Hiding fields in admin interface

[pgross]

I get the same problem with this field.  It doesn't show up in the
admin interface, but when I try to save the object, it blanks the field
and tries to update it in the database.  Since the field I want hidden
is a foreign key, the update statement dies saying "ERROR: invalid
input syntax for integer."

I can get around this by adding a _pre_save() method, looking up the
old value, and the setting it on the new object.  However, this is
pretty messy.

Is there a way to get the field to display on the admin as merely
uneditable text, then?  The core of my problem is that the foreign key
field points to a table that is huge (tens of thousands of values).
When the admin page loads, it makes a drop down box with all of these
values.  Therefore, the admin page size is really large and it takes a
long time to load.  I would rather just show the text of the field or
hide it altogether, without showing a drop down of all the possible
values.

Re: Hiding fields in admin interface

[oggie rob]

Did you try the "editable=False" argument, as in:
class MyModel(meta.Model):
   myField = meta.CharField(maxlength=20, editable=False)

Hiding fields in admin interface

[pgross]

Is it possible to hide fields in the admin interface?  I want my admin
interface to be able to modify only some fields on an already created
object.  I want the fields that aren't displayed to merely stay the
same.  However, if I leave the undesired fields out of the fields list,
I get errors when I try to save.  I think it blanks those fields out
rather than just leaving them how they were.
