How to customize fields in django rest framework serializer
I want to create a new record in database, I set a model like below: class FooModel(models.Model) subject_key= models.CharField(max_length=2) subject= modeels.CharField(max_length=100) What I want to do is this: field 'subject_key' should be given by the client, and using the subject_key, the server will find value 'subject' and put it in the database. So I tried to use ModelSerializer to create a new record. class FooSerializer(serializers.ModelSerializer): class Meta: model = FooModel def get_subject(self, obj): if obj.subject == 'SO': return 'Stack Overflow' else: return 'Nothing in here' and main running code inside view rest api is: def create(self, request, *args, **kwargs): serializer = FooSerializer(data=request.data) if serializer.is_valid(raise_exception=True) serializer.save() foo = serializer.data I checked it successfully create a new record in database, but the new record has NULL with the column 'subject' What should I do to dynamically set the field value inside serializer? -
class based view attributes

Is there anything else I can do to this for better performance?
Am trying to write an API using Django Rest Framework, which many applications will look up to, but I think what I have done is not robust enough for Production. Coming from a Ruby environment, its advisable to add indexes to db in few cases so as not to have a very slow response.

How to get a video snapshot (thumbnail) of a video being uploaded?
There seems to be a large variety of answers, and a lot of outdated packages so some direction would be nice. What's the best way to go about it?

Access model instance in generic.DetailView
Is there a way to access the model instance that is going to be presented in a generic.DetailView in views.py before the template gets rendered? Something like the hypothetical function here: class MyModelDetailView(LoginRequiredMixin, generic.DetailView): model = MyModel template_name_suffix = '_details' def do_some_initial_stuff(model_instance): # do stuff to model_instace, # like assigning fields, creating context variables based on existing fields, etc. Ultimately, I would like have a user click a button for a specific model instance in one template, then get directed to this generic.DetailView template where the model is presented with some of its field values changed and some other stuff (eg. the model may have a field that acknowledges that the this user clicked the button in the previous template). Suggestions on the most efficient way to do this would be appreciated. Thanks :) -

Django or conventional PHP?
Currently, I am the president and the code head of my school's IT club. The thing is, I made a website for club (which is yet to be surfaced online). I used basic HTML, CSS, JS and PHP. For now, I got the website running on Apache localhost with phpmyadmin. The dilemma I'm facing is, should I use Django instead? For now, I can code really well in Python, but have no experience in Django. The specifications of the website are: The website has a registration page using which school admins can register students for the IT fest that we are organizing. The website has an 'Events' page where all the events we have conducted or will conduct will be displayed. This info will be stored and retrieved from the database. For now I got my Events page to work by implementing a PHP loop for creating divs. The homepage has some good looking CSS and JS scroll animations. This definitely is a small scale website (don't get me wrong, complete website has not been described above). The trouble is, no one seems to take interest in coding or event organizing or anything that our group stands for. I have … -

Difference between installing by pip and installing globally
I am workikng with Python/Django web application, in Amazon EC2 / Debian series operating system. Application has Python setuptools library as dependency. So I installed setup this lib by this command globally: sudo apt-get install setuptools But this didn't work - application says dependency didn't resolved correctly. After some googling, I have found solution, like this: pip install setuptools. This worked for me. But I have a question - what's difference between these two? Of course, I didn't activated virtualenv, so it seems setuptools is installed globally. Would you like to bring me your experience? Please help me. -

dynamic form template based on the field type
I am doing the django project right now. I love the principle of DRY. I have a form which can be applied to all other pages which needs it. I mean a generic form based from django docs. But in the form, there can be select type, file upload, checkbox, radio etc which I dont like the design of native html. I want to leverage the design of material with some customization. I want it be done in template not from the forms.py. How can I do it? Below is my form and my form has checkbox, file upload and multiple select which I need to customize. In a nutshell, my question is how do I make my generic form designer friendly? form.html <form class="form" role="form" action="" method="post" enctype='multipart/form-data'> {% csrf_token %} {% for field in form %} {% if field.errors %} <div class="form-group label-floating has-error"> <label class="control-label" for="id_{{ field.name }}">{{ field.label }}</label> <div class="col-sm-10"> {{ field|add_css:'form-control' }} <span class="help-block"> {% for error in field.errors %}{{ error }}{% endfor %} </span> </div> </div> {% else %} <div class="form-group label-floating"> <label class="control-label" for="id_{{ field.name }}">{{ field.label }}</label> {{ field|add_css:'form-control' }} {% if field.help_text %} <p class="help-block"><small>{{ field.help_text }}</small></p> {% endif %} … -

I'm trying to integrate Apache Solr with my Django blog application. I'm using Apache Solr 4.10.4 downloaded from https://archive.apache.org/dist/lucene/solr/4.10.4/. I started Solr in terminal by typing java -jar start.jar in terminal as normal user. I tried create a new core with following parameters: name: blog instanceDir: blog dataDir: data config: solrconfig.xml schema: schema.xml But I'm getting error while creating core: Error CREATEing SolrCore 'blog': Unable to create core [blog] Caused by: null Also below error occures when initalization: SolrCore Initialization Failures blog: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException Please check your logs for more information Directory structure in ~/Downloads/solr-4.10.4/example/solr/blog: pecan@tux ~/Downloads/solr-4.10.4/example/solr $ tree blog blog ├── conf │ ├── lang │ │ └── stopwords_en.txt │ ├── protwords.txt │ ├── schema.xml │ ├── solrconfig.xml │ ├── stopwords.txt │ └── synonyms.txt ├── data │ └── index │ ├── segments_1 │ ├── segments.gen │ └── write.lock ├── nfa_regexp_debug.log ├── nfa_regexp_dump.log └── nfa_regexp_run.log 4 directories, 12 files Could anybody tell me what I'm doing wrong?
