Gitlab Django - How to install chromedriver for splinter django test suite?
I am using splinter for my Django functional tests. All functional tests are working locally without fail. But as as soon, as I push my project on my gitlab repository and the pipeline runs through all of them, all django tests fail because of a missing chromedriver.

How to pass dynamically data into the xml tags
I have some xml/soap packs and i'd like to able to pass some data dynamically in some tags for example. I have the following xml packet. Payload = '''<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <BankAccountType>ChequeAccount</BankAccountType> <AccountNumber>0495028198</AccountNumber> </s:Body>\n</s:Envelope> ''' Instead of hardcoding these i'd like to able to have something like this so that from postman i can inject directly inject some params such as bank_acc_type and account_number. bank_acc_type = request.POST.get('bank_acc_type') account_number = request.POST.get('account_number') Payload = '''<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <BankAccountType>{account_type}</BankAccountType> <AccountNumber>{account_number}</AccountNumber> </s:Body>\n</s:Envelope> '''.format(bank_acc_type=bank_acc_type, account_number=account_number) However, this solution of mine is not working.While debugging, bank_acc_type is taking None as well as account_number.

Django SelectMultiple widget in forms-How to have multiple values as initial selected data?
Have really been struggling with this one.I have a ModelForm to edit a Pizza object and one field is a Toppings postgres ArrayField. I'm using crispyforms. I want all the values that other users have entered into the ArrayField to be choices and to have the ones this user has already selected as initial values. I'm able to render all the choices correctly. But can only get 1 initial value to have the selected attribute on its option ie: <option value="Mushroom" selected="selected">Mushroom</option>. It won't let me pass a list or tuple in as self.initial['toppings'] = ['Mushroom','Tomato'], only a string self.initial['toppings'] = 'Mushroom' Anyone know how to fix this so I can pass in multiple selected choices as initial value for the form?

Create a print manager in django
I'm struggling with the following issue: I created a django app which work well. I' d like to add a print manager with a queue list of documents, then print them all in one time ! Here is my logic: I have many kind of text entries (id est many apps with entries i'd like to print....) for each text entry, i created a detailview (CBV): PrintEntry , which links to a new page with an appropriate template (using template inheritence, i extend each "kind" of entry with a specific template) Instead of clicking on "print" for each entry, i'd like to store them in a list to be able to print all entries in one time, later. Each list is obviously specific to each user. Until there, i don't have any problem. I created a Manytomany relationship between users and entries to store the url of the entry to print (url to PrintEntry). As long as i have different apps, for each app i have a PrintEntry class in my views, therefore there is different url stored. My strategy at this point is to generate a pdf file from each link stored, then merge all the pdf, and print … -
