How to serializer the openstack.compute.v2.server.ServerDetail?

Create password protected zip file Python
I'm using following code to create password protected zip file, from a file uploaded by user, in my Python34 application using zipFile. But when I open the zip file from windows, it doesn't ask for the password. I will be using the same password to read zip files from python later on. What am I doing wrong? Here's my code: pwdZipFilePath = uploadFilePath + "encryptedZipFiles/" filePath = uploadFilePath if not os.path.exists(pwdZipFilePath): os.makedirs(pwdZipFilePath) #save csv file to a path fd, filePath = tempfile.mkstemp(suffix=source.name, dir=filePath) with open(filePath, 'wb') as dest: shutil.copyfileobj(source, dest) #convert that csv to zip fd, pwdZipFilePath = tempfile.mkstemp(suffix=source.name + ".zip", dir=pwdZipFilePath) with zipfile.ZipFile(pwdZipFilePath, 'w') as myzip: myzip.write(filePath) myzip.setpassword(b"tipi") -

get_thumbnailer renders different image than source image
I'm using get_thumbnailer from the sorl-thumbnail package and the cached image that is rendered in the key value store (used in conjunction with S3 storage pointing to a bucket) is different image than the source (ie: image = ImageField(upload_to='images')) My use case is that I have images being uploaded from camera on mobile via a HTML5 <input type="file" accept="image/*" capture="camera">. For each image, a thumbnail is being produced via the get_thumbnailer method. From desktop and android uploads I have no issues, but apparently on iOS the image upload and generation via the get_thumbnailer is not consistent, for some mysterious reason which I have yet to determine. The url attribute that get_thumbnailer renders from one of the uploads from an iOS is a different image than the source image. I don't expect answers, but if you can give me some idea then that's good enough. Just say something and I will give you an up-vote. -

Add field to model dynamically and still work with migrations Django >= 1.10
Using Django v1.10 I found this comprehensive answer regarding having dynamic model and fields in Django https://stackoverflow.com/a/7934577/80353 As the answer is starting to show its age, I am hoping to garner some more updated answers. At the same time, my scope is slightly different from the original poster of the question which that answer belonged to. I will state my scope as below: Right now, I have models and fields defined by me the developer. But the user wants to be able to add new fields when they need to. I have been using django-migrations as a way to propagate changes. I prefer to continue to use postgres and continue to still have migrations for these user-defined fields. So that it's easy for me to troubleshoot in case the user did something wrong. Not all models will allow users to dynamically add fields. Only a select few models which I deem okay will allow dynamic fields. By default, when the user defines the field, there are only 4 kinds: integer, decimal, text, varchar. All are default nullable and blankable. The length will also be set default. Essentially, the user cannot define the length or the nullable, blankableness. The user also … -

I have a complex form: <<forms.py>> class AttributeOptionForm(forms.Form): option_name = forms.CharField(label="Attribute Option") class AttributeForm(forms.Form): attr_name = forms.CharField(max_length=100, label="Attribute Name") attr_options_list = [AttributeOptionForm(), AttributeOptionForm()] class ProjectForm(forms.Form): name = forms.CharField(max_length=250, label="Name") attr_form_list = [AttributeForm()] ProjectFrom holds at least one AttributeForm (which may grow on runtime) and each AttributeForm holds at least two AttributeOptionForm (which may also grow on runtime). You may think of any AttributeForm as a question with multiple answers (AttributeOptionForm), which I want the user to fill in. This is how I present the ProjectForm. <<project_form.html>> <form class="form-horizontal" action="" method="post" enctype="multipart/form-data"> {% csrf_token %} <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <span class="text-danger small">{{ form.name.errors }}</span> </div> <label class="control-label col-sm-2">{{ form.name.label_tag }}</label> <div class="col-sm-9">{{ form.name }}</div> </div> {% for attr_form in form.attr_form_list %} <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <span class="text-danger small">{{ attr_form.att_name.errors }}</span> </div> <label class="control-label col-sm-2">{{ attr_form.attr_name.label_tag }}</label> <div class="col-sm-9">{{ attr_form.attr_name }}</div> {% for option in attr_form.attr_options_list %} <div class="col-sm-offset-2 col-sm-10"> <span class="text-danger small">{{ option.option_name.errors }}</span> </div> <label class="control-label col-sm-2">{{ option.option_name.label_tag }}</label> <div class="col-sm-9">{{ option.option_name }}</div> {% endfor %} </div> {% endfor %} </form> In the form, in addition, there are an 'add_attribute_option' buttons (per attribute), 'add_attribute' button, and 'submit' button. How do I collect the data in my views.py file? … -

'NoneType' object has no attribute 'rsplit'
I'm not sure how to track down this error: I'm running a django app on Python 3.4 in AWS. I re-deployed a couple of hours ago and discoverd this error while trying to fix an error with environmental variables. I'm not sure where to start, or where I could have gone wrong. It seems to have something to do with mail, and while I did recently mess around with some mail code, commenting out such code did nothing to resolve the problem or change the error.
