Re: DJANGO ADMINISTRATION ERROR & TemplateDoesNotExist

The console does not seem to provide much information. It is simply stating that there is a 500 Server Error. I tried sifting for more details but there were none.

However, in the:

> heroku logs --tail

It simply mentions that none of the paths exist to the cart and the images that derive from the DJANGO ADMINISTRATION page. Strangely, all of the other pages and pictures on the website works. It is rather confusing to see only the store section of the site encountering this bug.

How could the title and header 1 be causing the Server Error (500)?

Why would this occur only upon publishing the website? It does not seem to be registering the images from DJANGO ADMINISTRATION. Also, when I click my cart icon after adding one of the non-image showing items, I receive an error 500 stating that the cart.html and only the cart.html TemplateDoesNotExist. It has the same settings as every other html page, what makes this single page unique to becoming an error 500?

Hello All! I need some help with a problem I have been struggling with. One of you generous geniuses has the answer I'm sure of it. I am working on integrating an export to csv button(link) on my template to export filtered data from one of my tables. I have previously only been able to dump the entire table to csv which isn't exactly what I need. So my thoughts were to place a button/link on the template passes a parameter(dictionary of my filter criteria) to a view named ExportSearch. The view then calls a function that I have defined to perform my filtered query to the table and then writes outs to csv. In theory I thought this should work but I keep getting errors that I have not been able to resolve and I am at the end of my knowledge capacity here. Applicable code below.

Hello dear,

add that app in settings.py in installed apps

Eg. "base.apps.BaseAppConfig"

Or simply

"base"

Kind regards Haris

Re: Error configuring URLs for a beginner

Do you have a urls.py in your 'app' folder? (And app is a reserved keyword, it would be better if you use some other name to avoid confusion even later )

Re: URL configuration error for a beginner

You need to replace apps.url with the name of the app ( which you might have created using python manage.py startapp <appname> and have a urls.py file in that app folder)

In the tutorial also, they first create an app 'polls' and then include 'polls.url'

It would be easier to solve your problem if you can post the directory structure here.

Arpana

I ended up with the following error when I run python manage.py runserver:

File "/home/me/website.com/project/project/urls.py", line 21, in <module>

path('app/', include('app.urls')),

...

urlconf_module = import_module(urlconf_module)

...

ModuleNotFoundError: No module named 'app.urls'

app is what is created by python3 manage.py startapp app

and project is what is created by python3 venv/bin/django-admin.py startproject project

can you please explain to me how to resolve? I am trying to read through different documentation of URL resolution and tried

from app import views

from app import urls

and did not work. It seems I have a long way to get used to the directory structure and naming convention and appreciate a jump start please

thank you,

Manal

DJANGO ADMINISTRATION ERROR & TemplateDoesNotExist

I logged into the ADMIN PORTAL and saw that there was an image for each item in the ADMIN PORTAL.

Strangely, when returning to the website, I am unable to actually "see" the pictures - they are blank with the no file icon in the top left. This was not the case back in the testing environment.

Why would this occur only upon publishing the website? It does not seem to be registering the images from DJANGO ADMINISTRATION. Also, when I click my cart icon after adding one of the non-image showing items, I receive an error 500 stating that the cart.html and only the cart.html TemplateDoesNotExist. It has the same settings as every other html page, what makes this single page unique to becoming an error 500?

I would recommend finding some tutorial on how to use git (as that is
probably what you'll use anyway). Cannot really recommend anything
specific, but someone else might be able to.

It takes some time to learn even the basics and it might seem useless as
it is time not spend on writing code, but it can save you so much time
later on, so it's definitely worth it.

Has helped me many times in frustrating situations like the one you have
right now, and you will have situations like that again, even after many
years of writing code.

We're only humans after all and most of us cannot remember the point of
the code we wrote two days ago, so it's extremely helpful to have tools
to help you remind you what you did (and why) two years ago.

Kind regards,

Kasper Laudrup

So you probably just need to ensure that the user running your Django
code has write access to BASE_DIR / media.

Now it's up to you to figure out who that user is, what that path is and
ensure the that path has the proper owner and permissions.

I personally wouldn't be afraid to add some print statements to the
deployed code for "dirty debugging" in cases like this, but that
definitely depends on you and your usecase.

Kind regards,

Not that it might help you right now, but it is usually a good idea to
keep your things in revision control (e.g. git) and then commit often.
Especially when you have something that works and want to experiment
with something new.

That way you can easily see the differences between the state of the
code when it worked and the current broken state or use something like
"git bisect".

Re: NoReverseMatch at /searchlit/customsearch and bigger problem of exporting a filtered queryset

Thanks coolguy I changed my urls.py to this and that resolved the error:

from django.urls import include, path

from . import views

from .views import search

app_name= "searchLit"

urlpatterns=[

path('customsearch/', views.search, name='search'),

path('exportlit/', views.searchLit_export, name='SearchLit_export'),

path('noccustomsearch/', views.nocSearch, name='nocSearch'),

path('exportnoc/', views.noc_export, name='noc_export'),

path('exportSearch/<str:params>/', views.exportSearch, name='exportSearch'),

]

I now am getting:

Reverse for 'exportSearch' with arguments '("{'circuitid': '', 'bandwidth': 'Select Bandwidth', 'region': 'Central', 'carrier': 'Select Carrier', 'status': 'Select Status', 'segmentname': 'Select Segment', 'mrcnew': '', 'diversity': 'Select Option', 'kmz': 'Select YES/NO', 'multipleSearch': ''}",)' not found. 1 pattern(s) tried: ['searchlit\\/exportSearch\\/(?P<params>[^/]+)\\/$']

When I try to use this code in my template to pass a dictionary(containing my search parameters) to the export function to export only filtered table data:

template:

views.py:

def exportSearch(request, params):

params = ast.literal_eval(params)

search_vector = SearchVector('circuitid', 'carrier', 'pathname', 'segmentname', 'segmentid', 'alocationaddress', 'alocationcity', 'alocst', 'zlocationaddress', 'zlocationcity', 'zlocst', 'handoffalocaddress', 'handoffalocst',

'handoffaloccity', 'handoffzlocaddress', 'handoffzloccity', 'handoffzlocst', 'latestjiraticket', 'installciopsticket', 'retermciopsticket', 'discociopsticket', 'notes', 'diversitynotes')

allcircuits=filterCircuits(params, search_vector)

return render_to_csv_response(allcircuits)

I assume that I need to use a different path converter but I am unsure. Any tips am I thinking about this the right way or is there a better way to do what I am trying to do?

You can't have the same name twice. You need to change the name for one of the followings:

Reverse method requires a url identified by name parameter which must be unique. Its looking for search and it find it on two places so you are getting this error.

I understand that. My point was that not not only didn't it solve your
problem, you opened up for a lot of other potential issues later on.

As long as you don't share your code it's hard to help you much more,
but have a look at the path you specify to pdformfill in line 441 of
your views.py file and see if my suggestions might be of any help.

your views.py file and see if my suggestions might be of any help.

Kind regards,

Re: Premission Denied - Apache

Hi Kasper,

When I was running with the django local server, I have permission and works good. The error occurs when I publish the site with apache2

I gave 777 permission because I was trying to do it (give permission).

Please don't do that. That's a huge security risk and can cause all
kinds of other problems.

It is hard to know how to solve your issue since you haven't shared any
of your code, but I'd suggest you specify a base path for where you save
your PDF files in your settings.py, ensure that the user running your
django code has write access to that directory (and only that directory)
and then ensure you use that path when saving your PDF files (ie. no
relative paths).

Kind regards,

Kasper Laudrup

UpdateView Redirect

I have got myself into somewhat of a pickle.

Currently I have the following url structure:

path('<uuid:pk>/', views.PublisherDetailView.as_view(), name='publisher_detail'),

path('<uuid:pk>/update/', views.PublisherUpdateView.as_view(), name='publisher_update'),

In my views the following:

class PublisherUpdateView(UpdateView):

model = Publisher

template_name = "catalog/publisher_update.html"

fields = (

"name",

"address",

"city",

"state_province",

"country",

"website",

)

def get_success_url(self):

return reverse_lazy("catalog:publisher_detail", kwargs={'pk': self.object.id})

And the link in my template is:

<a href="{% url 'catalog:publisher_update' publisher.id %}" class="btn btn-sm btn-info">Update</a>

Everything works fine at this point.

However my url structure now need to become:

path('<slug:slug>/<uuid:pk>/', views.PublisherDetailView.as_view(), name='publisher_detail'),

path(<slug:slug>/'<uuid:pk>/update/', views.PublisherUpdateView.as_view(), name='publisher_update'),

My question is how do I account for this in my views?

Any help would be appreciated
