fadeToggle corresponding div with regex in django
I am displaying small content(id=showmore_ and with the forloop counter) (30 words) of the comment initially. I want to hide it and show all the content of id more_content_ of same loop counter. HTML: <div class="comment"> Comments ({{discuss.get_comments|length}}): {% for comment in discuss.get_comments %} <div id="showmore_{{ forloop.counter }}"> {{ comment.commenter.get_full_name }} - {{ comment.body|truncatewords:30 }}... <em>Read More</em> </div> <div id="more_content_{{ forloop.counter }}" style="display: none;"> {{ comment.body }} </div> <div> {% for subcomment in comment.get_subcomments %} <div>{{ subcomment.body|truncatewords:30 }</div> {% endfor %} </div> {% endfor %} </div> jQuery: $(document).ready(function(){ $('div[id^="showmore_"]').click(function(){ $('div[id^="more_content_"]').fadeToggle(); }); }); When I give same id to all( eg. showmore or more_content), every element gets hidden or shown. What do I do? -
How to use OAuth token to connect to ejabberd in browser?
I want to develop a chat app in django using ejabberd. Following are the use-case :- Registration When user register with my app, I'll create a new user in ejabberd, using same username and password. Login For login, I am going to provide django-based login form. Based on the successful login, I'll log user into ejabberd from my app, so that ejabberd remain transparent to user. Here, I am planning to use OAuth based authentication to log user into ejabberd. Once OAuth token is obtained from ejabberd, I'll pass it to client(browser). Client will save the token. User will make connection directly will ejabberd, using that OAuth2 token received. From thereon, browser will directly communicate with ejabberd. Logout For logout, User will send request to my app. My app will logout user from ejabberd. I am able to perform steps 1 and 2 successfully. But I am facing issue in connecting to ejabberd from browser using OAuth token. I am not aware about how to do so in strophe.js. Is there any way to achieve this ? Is there any alternative library exists, which help in achieving this at client side ? Moreover, Any example or suggestion regarding improvement/problem in … -

DRF api filtering room that has not reservation
i have this scenario. User will reserve room in date range(E.g from 2017-06-08 - to 2017-07-09) Also user can choose private room or shared room.

Overriding clean() method of Parent django form in child/inherited form
I am really having a hard time figuring this out. The bottom problem is that I need to somehow either set initial value for password field or override the way the method validate_member is called. I have this form, which is called when a member needs to register to the system directly: class NewMemberForm(forms.Form): ''' Called when user wants to register with our system from web/mobile. Ask password here ''' firstName=forms.CharField(max_length=25,required=True,widget=forms.TextInput()) lastName=forms.CharField(max_length=25,required=True,widget=forms.TextInput()) birthdate=forms.DateField(required=True) gender=forms.ChoiceField(choices=Profile.GENDER,required=True) idnumber=forms.CharField(required=False,max_length=25) phone=forms.IntegerField(required=True) email=forms.EmailField(required=True) password=forms.CharField(max_length=16,widget=forms.PasswordInput()) memberType=forms.ChoiceField(choices=Profile.TYPE_OF_MEMBER,widget=forms.Select()) maritalStatus=forms.ChoiceField(choices=Profile.MARITAL_STATUS,widget=forms.Select()) def clean(self): ''' Grouped cleaning ''' self.cleaned_data=super(NewMemberForm,self).clean() validate_member_form=validate_member(self.cleaned_data,False) #do we have error messages now? if len(validate_member_form[0])>0: #yes we have error messages raise forms.ValidationError(_(validate_member_form[0]),code='invalid') return validate_member_form[1] the validate_member function is used during editing and adding information, thus cleaned the clean() to keep things DRY. Now, I have another scenario in which a member could be registered by another member (with some rights). In that case, the password and membertype fields are not needed with one new field added to the form named role; so I decided to inherit the form: class MemberAddForm(NewMemberForm): #memberType=forms.CharField(initial='Individual',required=False,widget=forms.Select()) #iignored: here to simple override the Required declaraton in memberform #password=forms.CharField(max_length=16,widget=forms.PasswordInput(),required=False,initial='111111') #note pwd is ignored during saving and a new is generated role=forms.ModelChoiceField(widget=forms.Select(),required=True,queryset=Activity.objects.filter(active='Active').only('id','name'),empty_label=None) def __init__(self,*args,**kwargs): super(MemberAddForm,self).__init__(*args,**kwargs) self.fields['password'].initial='123456' #note … -

Connecting Two Users together (Django Rest) to 'grant' access to each other's User Model
In my Django Rest API, I have a large user serializer where I pull in all 'attached' models with a depth of 1. I have two users connect to each other like a 'friendship' (They can only have one connection). User A -> sends req to userB (In the Relationships model: user: userA_id, partner: userB_id is created). userB gets a notification on login pertaining to the request. UserB can choose to accept or deny. If they accept: (In the relationships model: user: userB_id, partner: userB_id is created). Then on the client-side, a check is done to see if the fields exist for each other on the relationship model. This isn't ideal, because a client could still always pull down info if they just made their own modified client... On the service side, how is it possible to only see data if the the two users match? (the User serializer has a lot of attached models with a depth of 1 so I can build the client page). Thank you. -

How to test email sending after http request in Django
I just read this question. A lot of people suggested using the django.core.mail module for unit testing email sends like so: def test_send(self): mail.send_mail('subject', 'body.', 'from@example.com', ['to@example.com']) assert len(mail.outbox) == 1 But what if your test involves sending an http request with django.test.Client? Then you would not have access to that mail instance from the unit test. In this scenario, how could I test an http endpoint which automatically sends an email? -

Tamporarily saving and sanitizing image objects in Django
I'm creating a Django website where users post details of used items they want to sell/barter. When posting an item, the second-last step is to upload (upto 3) photos of the item on sale. The last step is to provide personal details (name, address, mobile). After this, the ad is finalized and goes into a "pending approval" queue. I don't want to save photos to the DB until an advert is finalized. Hence I'm thinking I'll temporarily save a reference to the UploadedFile object retrieved from the form like so: request.session["photo"] = form.cleaned_data.get('photo',None) So far so good, or is this problematic? Assuming everything is correct so far. Next, once ad is final, I'll save the images to my storage backend and pop photo from the request.session dictionary. But what if the user drops out before finalizing the ad? How would I handle cases where a request.session["photo"] entry was created, but the user never finished the ad? Where are UploadedFile objects saved? Basically, I need an efficient way to process 'orphaned' request.session image entries and related UploadedFile objects. -

Where does Django controller logic live?
I'm having trouble working out where to put controller logic in my Django project. I have models for players (think like chess players) who will be rated by ELO scores. After a round, two players have their ELO scores modified and updated. The next matches are chosen based on the players who have so far participated in the least number of contests. class Player(models.Model): tournament_class = models.ForeignKey(Topic, on_delete=models.CASCADE) # each player is part of a single tournament class name = models.CharField(max_length=200) contests = models.IntegerField(default=0) last_contest = models.IntegerField(default=0) # round number of last contest participated in ELO = models.FloatField(default=1000) # current ELO ranking Where would I put control logic like the following functions? def select_candidates() # return candidates who have participated in the least number of contests def update_ELO_scores (winner,loser) # updates ELO scores based on match results From what I have read, I think these functions I want to write should not live in the models, as these functions do not relate to single object instances. They might belong in a custom manager, as they do work on QuerySets, or do they belong in a QuerySet manager or a seperate package (python file)?
