Send PDF file path to client to download after covnersion in WeasyPrint
In my Django app, I'm using WeasyPrint to convert html report to pdf. I need to send the converted file back to client so they can download it. But I don't see any code on WeasyPrint site where we can get the path of saved file or know in any way where the file was saved. If I hard code the path, like, D:/Python/Workspace/report.pdf and try to open it via javascript, it simply says that the address was not understood. What is a better way to apporach this issue? -

How to export and import data and auth information in Django?
I'm working on a project which is already public so there are some Order objects and User objects in the database (couple of people has registrated and created some orders). Now I'm changing some things in this project including Order model (added some fields like created_time etc.) So my new database (sqlite3) has very similar schemas compared to old but it's not the same. How can I add old users and Order objects into the new db? Is there some plugin or best practise? There should be no problem with Users because their schema hasn't changed but I suppose that app_users table is not enough to copy. class Order(models.Model): customer = models.ForeignKey(User, related_name='orders', blank=True, null=True) first_name = models.CharField(max_length=40,verbose_name=u'Vorname') last_name = models.CharField(max_length=40,verbose_name=u'Nachnahme') dry_wood = models.PositiveIntegerField(blank=True, null=True, default=0,verbose_name=u'Trockenes Holz') wet_wood = models.PositiveIntegerField(blank=True, null=True, default=0,verbose_name=u'Halb trockenes Holz') briquette = models.PositiveIntegerField(blank=True, null=True, default=0,verbose_name=u'Brikettes') stelinka = models.PositiveIntegerField(blank=True, null=True, default=0,verbose_name=u'Klein Holz') street = models.CharField(max_length=200, verbose_name=u'Straße', null=True, blank=True) number = models.CharField(max_length=40, null=True, blank=True, verbose_name=u'Hausnummer') city = models.CharField(max_length=100, verbose_name=u'Stadt', null=True, blank=True) psc = models.CharField(max_length=40, null=True, blank=True, verbose_name=u'PLZ') telephone = models.CharField(max_length=50, null=True, blank=True, verbose_name=u"Telefon Nummer") telephone2 = models.CharField(max_length=50, null=True, blank=True, verbose_name=u'Telefon 2') email = models.EmailField(null=True, blank=True,verbose_name=u'Mail') time = models.TextField(null=True, blank=True, verbose_name=u'Kommentar') price = models.DecimalField(max_digits=20, decimal_places=2, blank=True, null=True) text_order = … -

Finding out the file name in a FileUploadHandler
I am rolling my own fileupload handler in django and would like to know the file name. I am supporting more than one file format and want to do different processing in the receive_data_chunk method depending on which file format the uploaded file has. I thought I would be pragmatic and just judge file format based on file ending but I can't figure out how to get hold of the file name. If I try to extract the file name with something like the following code: if request.method == 'POST': p = re.compile('^.*\.sdf$', re.IGNORECASE) if ( p.search(request.FILES['filecontent'].name) ) : self.sdf = True else: self.sdf = False It seems I never reach the receive_data_chunk method. I presume the call to request.FILES trigger the loading somehow and then it's already done? How can I do different processing based on file ending in my receive_data_chunk method? -
Auto-fill Django OneToOneField

how to add href value in django view
I am working on a project using django, in this i have a module which shows the listing of users in a table format, the data of users returns from django view to django template using ajax, so the action values with buttons also have to be returned from view to template in json response, as we usually do in bootstrap ajax datatables. Now the problem is that i have to set href value in django view. Code in view is :- for user in users: actionValues='<a title="Edit" class="btn btn-sm green margin-top-10" href="'"><i class="fa fa-edit"></i></a> <a title="View" class="btn btn-sm blue margin-top-10" href="'"><i class="fa fa-view"></i></a>'; inner_data_list = [ i, user['first_name'], user['last_name'], user['email'], user_type, '<div id=%s class="bootstrap-switch bootstrap-switch-%s bootstrap-switch-wrapper bootstrap-switch-animate toogle_switch"><div class="bootstrap-switch-container" ><span class="bootstrap-switch-handle-on bootstrap-switch-primary">&nbsp;Active&nbsp;&nbsp;</span><label class="bootstrap-switch-label">&nbsp;</label><span class="bootstrap-switch-handle-off bootstrap-switch-default">&nbsp;Inactive&nbsp;</span></div></div>'%(user['id'],checked), user['date_joined'], actionValues ] datalist.append(inner_data_list) As you can see in code there is a variable actionValues it contains two buttons, related to each listing , Now what i have to do is i have to link these two buttons to function edit_details and view_details respectively. So how can i link these two buttons to their respective function in view. -
how to test uwsgi app
I a question about monitoring uwsgi on multiple nodes So i have 2 instances: "a" instance => nginx (as a balancer ) + uwsgi app (django) "b" instances => uwsgi app (django) I had few times situation when uwsgi raced to 100% CPU and respond 499 http code to each http request. Everything I needed to make app works - just to restart uwsgi (supevizorcrl restart uwsgi). So now I want to setup some monitoring. I consider using monit. It can monitor how much cpu process uses. But I don't know how to check the 2-nd case - http code, especially I don't have nginx on the 2-nd instance. Is it possible to make request to uwsgi directly ? or how to check uwsgi is working properly ? Can someone advice how to setup monitoring in such case ? -

Accessing users groups through attributes / foreign keys in Django
I'm trying to access my users groups in Django, but keep getting auth.Group.None as the result. When in the django shell I'll first create a group, then a user and add the user to the group. After this, I try to print the users groups, like so: from django.contrib.auth.models import User, Group Artists = Group.objects.create(name="Artists") Artists.save() Rihanna = User.objects.create_user(username="Rihanna", password="newpassword") Rihanna.save() Artists.user_set.add(Rihanna) # Save both of them again just to double check Rihanna.save() Artists.save() # Now try to access Rihanna's groups through her attributes: print Rihanna.groups, Rihanna.groups.name and the results are >>> auth.Group.None None What I'd like to happen is for it to print the groups name. I know I can query the members of a group by the filter and get commands, but I'd like to access the groups straight through a users attributes/foreign keys. Any idea what I'm doing wrong? -

How to deploy react.js webpack with django to heroku?
I have a django backend and react.js frontend along with webpack. I've set everything up locally as per this page: http://owaislone.org/blog/webpack-plus-reactjs-and-django/ and have my dev server running and all is peachy. For my production webpack file I've copied the same exact one as on the site. However I would like to deploy to heroku and this is where I get stuck. Do I need to replace my webpack-dev-server with some kind of express server on production? Can I just run django and serve up static javascript files instead? To generate these files I've tried running: "webpack webpack-config.prod.js --progress -p" however I get a bunch of "Cannot resolve module 'fs'" errors but I do notice it generated a 900kb js file in assets/bundles. Also if I try running "webpack webpack-config.prod.js --progress -p" on my local machine (without the dev server) and go to a django route I get this in my console: GET http://localhost:3000/assets/bundles/main-62ddfced1c44b3270fa7.js net::ERR_CONNECTION_REFUSED I have spent quite a few hours getting this to work, setting up the dev environment was a lot faster.

Django How PermissionRequireMixin class works in code level?(I am even looking into mixins.py in auth folder)
I would like to know how PermissionRequireMixin works in Django. (I couldn't find any question explaining how PermissionRequireMixin works in very detail. I am looking into code 'mixins.py' in path of 'django.contrib.auth'.)
