Hi, I'm trying to make a molecular mass calculator webpage, where a user

I have the html form set up, but when I click "submit", the page just

I'm interested in molecular mass calculation mainly because of isotopic
variances. How do you account for them? They seem to vary somewhat
depending on the laboratory doing the work. I'm building an application
and have made an interface to collect molecular weight from NIH or
Chemspider. But I would prefer to calculate weights than go and get them.
On your Django question, I would be creating a database record for each
substance formula and calculate the molecular weight in models.py then
put the value in a field just prior to save(). Once you have the data
you can just redisplay the same page.
Otherwise, detect that you actually have a molecular weight and display
a different page.
Here is an excerpt from my own Substance model ...
formula = models.CharField(max_length=LARGE)
molecular_weight = models.DecimalField(null=True, blank=True,
max_digits=10,
decimal_places=4,
default=0.)
... and this is where I would do the calculation ...
def save(self, *args, **kwargs):
self.molecular_weight = CalcMolecularMass(self.formula)
super(Substance, self).save(*args, **kwargs)

What I want to happen is:
1. User inputs formula in form on index.html(ex. H2)
2. Form data is processed using the code that I put in the result view
3. Result is outputted in result.html
However, I'm not sure how to do this, as I've looked through the
tutorial and form docs.

Converting to Custom User Model (Django 1.5)
We are currently using the following user model setup: settings.py: AUTH_USER_MODEL = 'auth.User' userprofile.py: class UserProfile(DirtyFieldsMixin, User): Is it possible to change these to the following and have South take care of the data as not lose anything? settings.py: AUTH_USER_MODEL = 'userprofile.UserProfile' userprofile.py: class UserProfile(DirtyFieldsMixin, AbstractUser): I have looked through here and the rest of google and all the answers show created a new custom user that you copy everything to. Is it possible to continue to use our UserProfile but just convert it to extend AbstractUser as made possible in Django 1.5 (which we are currently using)?

Re: Introducing myself and my first question
Hey Martin,
I can guarantee you that PyCharm is totally worth buying. It will speed up
your development drastically and it works really well with Django.
Autocompletion both in Python and template code, syntax highlighting in
both, easy Option+Enter imports, navigation through code, refactoring. You
name it has it. Just the merge tool is worth those $99.
Cheers,
M

Thanks to you both.
I know the URL, Ariel, and I will look at it when beginning the
implementation.
Thanks Cal for the comments. I've been heard very well about Sublime Text
and I'm planning ot use it, not as a IDE, but for other issues as a
complementary editor.

Re: Newbie: Complete environment setup(virtualenv, pip, eclipse, git...)
Thanks Mulianto, ngangsia and Tom.
I'm working in Ubuntu but I will take advantage of your instructions
ngangsia when setting up all the "machinery".
Thanks also Tom, for the advice and the requirements tip, as this will be
another thing we're trying for the first time in future.

Hi Martin
Everything you've said seems on the right path. For your couple of queries:
You need to activate the virtualenv each time you want to run python
within that environment. You simplify this by putting the path to the
environment in to Eclipse as this also 'activates' the environment, so
that every time you run something through Eclipse you do not need to
first activate the environment.
Typically, you would need to activate the environment to do things
like run your project from the command line, or install python
packages in to the environment.
Another useful technique I use is to have a "bootstrap" script, a
simple shell script that installs a virtualenv if it does not already
exist, activates that environment; and then installs or upgrades all
the packages listed in requirements.txt. This script can then be run
whenever to ensure the environment is up to date and correct.
#!/bin/sh
if [ ! -d env ]; then
virtualenv env
fi
ln -sf ./env/bin/activate
. ./activate
pip install --upgrade -r requirements.txt
Give your projects differently named environments - don't call them
all 'env', or you will inevitably install something in the wrong env.
When writing your requirements file, you can track security releases
of libraries by specifying like this:
django>1.6<1.7
This would install the latest security release in the 1.6 line of
django, and every time you re-run bootstrap, it will install any
Question about including CSRF token.
Hi Everyone, I am writing a website using Django, and getting confused about CSRF token, I understand I need to include the csrf token on my web page to prevent the CSRF attack. However, I am also working on a mobile app, which will sends request to my website API, and get response back, how should I handle the CSRF token problem in this case?

Re: Newbie: Complete environment setup(virtualenv, pip, eclipse, git...)
If you are working with windows , let me give you a very simple guide. Google and download setuptools.exe and install in to your computer. First install python 2.7 ans set the python path Then move to this directory C:\Python27\scripts in the windows command . You should run easy_install pip Then also run easy install virtualevn and your virtual env will be install in that directory alone. Then to create you environment you run this command virtualenv --no-site-packages [name of your environment] for example virtualenv --no-site-packages django_test Then to activate this environment you type this command [name of your enviroment]\scripts\activate make sure you do all this in that directory abovee for example C:\Python27\scripts\django_test\scripts\activate then your environment will be activated Then move to this directory cd django_test you path will become C:\Python27\scripts\django_test. Then run pip install django [you can specify the version] then when django is install move to the directory as so run the dir command you will see the downloaded django move to the downloaded django as using this command cd Django-1.4.3 depending on the version of your django To install the django now in to the system , type setup.py install in this directory C:\Python27\scripts\django_test\Django-1.4.3. That will depend your directory django will be install then move to cd django C:\Python27\scripts\django_test\Django-1.4.3\django move to C:\Python27\scripts\django_test\Django-1.4.3\django\bin\ the u will have to create your projects run this command withtin that sam directory C:\Python27\scripts\django_test\Django-1.4.3\django\bin\django-admin.py startproject [name of your project] Then you can figure out the rest Thanks -- You received this message because you are subscribed to the Google Groups "Django users" group.

Initial data in 1.7
Hi there, as pointed in documentation [1], automatic loading of initial data from initial_data.[xml/yaml/json] is deprecated since 1.7 in favor of data migrations. However, there are several drawbacks and differencies: 1. Data migration is executed only once (unless migrations are rewinded to the beginning), while initial_data were loaded everytime with syncdb command. Former behavior ensures that the right data are present in table. Of course it can be used with data which doesn't change often (like sites). 2. It's not straightforward to provide initial data to existing or third-party apps. One have to create custom app to store migrations (like 'initial_data') and then create *empty* models.py in app directory. Otherwise migrations won't be loaded, as already pointed in [2]. What's the correct way to provide initial data to apps which needs to be present everytime, otherwise website won't work (like sites, auth token, superadmins, etc.)? Have anyone solved this issue recently in Django 1.7? Thanks, Tom [1] https://docs.djangoproject.com/en/dev/howto/initial-data/#automatically-loading-initial-data-fixtures [2] https://groups.google.com/d/msgid/django-users/20140715142108.GA10827%40rkade-thinkpad -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: managing temporarily created files
Dear Paul, Thank you for the fast and useful reply. However, I have two questions. According to django documentation, HttpResponse accepts string parameter. Does it also accept binary data. I am using python3 in which string is a unicode string and binary data are stored in bytes class. Second, I am planning to use ezodf library to create odt files. It appears that there is no way I can access data from memory in this library. do you know of any good python library that can create and modify odt files? Thank you على الإثنين 21 تـمـوز 2014 18:49, كتب Paul J Stevens: On 21-07-14 17:09, alghafli wrote: I want to dynamically create a temporary odt file and upload it to the client. The file is dynamically created based on GET request parameters. It basically searches the database and fills the odt file with information. This file is temporary and should be deleted after the upload finishes. tempfile.TemporaryFile is what you seem to want. The file object is deleted automatically. fd = tempfile.TemporaryFile() fd.write(odt_data) fd.seek(0) return HttpResponse( fd.read(), content_type='application/vnd.oasis.opendocument.text' ) But then you might as well skip the tempfile feature, and stream directly from memory: return HttpResponse( odt_data, content_type='application/vnd.oasis.opendocument.text' ) Here is how I am planning to do it. The view function creates the file and fills it with information. The file is created in a directory which is added to the STATICFILES_DIRS. The view then redirects to the file url and the client downloads the file. Since your odt data is for one-time-only usage, you don't need to put them in any kind of STATIC_FILES directory. That feature is of use to offload download performance to the web-server, but for one-time-only downloads there is no point. To delete the files, I am planning to create a class that handles temporary file creation and deletion. The class forces an upper limit to temporary files number, say 10. Any file created after 10 files will make the class delete older files based on modification time. I might as well create a thread that would delete files regularly but it would be a bit more complicated and unnecessary for this specific project. Done already by the tempfile.TemporaryFile class, and totally redundant when streaming from memory. -- You received this message because you are subscribed to the Google Groups "Django users" group.

To be honest at this moment I am not sure of pros & cons of using mySQl v/s postgres I will do some more research on that and see if switching to postgres SQL is an option. -Subodh On Fri, Jul 18, 2014 at 9:11 PM, carlos wrote: > Hi, Subodh right now i find information for multi-tenant project in django > and see > this app, i never used only i read information for the future project. > > https://github.com/bernardopires/django-tenant-schemas > > maybe help you. > > Cheers > > > On Fri, Jul 18, 2014 at 6:56 PM, Mike Dewhirst > wrote: >> >> On 19/07/2014 3:51 AM, Subodh Nijsure wrote: >>> >>> This is the first time I am trying to implement multi-tenant setup >>> under django and hence the question. >>> >>> Problem/Setup >>> - There are two companies signed up for service from portal I am >>> developing say CompanyA, CompanyB. >>> >>> - Each user with this setup is identified by unique email address, >>> users login using their email address and password. >>> >>> - CompanyA has following users >>> A-tech1 >>> A-tech2 >>> A-tech3 >>> >>> - CompanyB has following users >>> B-tech1 >>> B-tech2 >>> B-tech3 >>> >>> Requirements: >>> >>> 1.

The file object is deleted automatically. fd = tempfile.TemporaryFile() fd.write(odt_data) fd.seek(0) return HttpResponse( fd.read(), content_type='application/vnd.oasis.opendocument.text' ) But then you might as well skip the tempfile feature, and stream directly from memory: return HttpResponse( odt_data, content_type='application/vnd.oasis.opendocument.text' ) > Here is how I am planning to do it.

That feature is of use to offload download performance to the web-server, but for one-time-only downloads there is no point. > To delete the files, I am planning to create a class that handles > temporary file creation and deletion.

Done already by the tempfile.TemporaryFile class, and totally redundant when streaming from memory. -- Paul J Stevens pjstevns @ gmail, twitter, github, linkedin www.nfg.nl/i...@nfg.nl/+31.85.877.99.97 -- You received this message because you are subscribed to the Google Groups "Django users" group.

managing temporarily created files
Hello django community, I am currently developing my first web application. Since I am new to web development, I thought I should seek advice on what I am trying to implement at the moment. Before I start, here are my questions: *can django do this?**if not, is there a python library that can do this? if not, am I doing it right?* I want to dynamically create a temporary odt file and upload it to the client. The file is dynamically created based on GET request parameters. It basically searches the database and fills the odt file with information. This file is temporary and should be deleted after the upload finishes. Here is how I am planning to do it. The view function creates the file and fills it with information. The file is created in a directory which is added to the STATICFILES_DIRS. The view then redirects to the file url and the client downloads the file. To delete the files, I am planning to create a class that handles temporary file creation and deletion. The class forces an upper limit to temporary files number, say 10. Any file created after 10 files will make the class delete older files based on modification time. I might as well create a thread that would delete files regularly but it would be a bit more complicated and unnecessary for this specific project.

Dictionary-style string formatting
Hi
Here it tells me that 'The given URL may contain dictionary-style string
formatting...':
https://docs.djangoproject.com/en/1.6/ref/class-based-views/base/#redirectview
and to get it to work I have to put an 's' at the end of the url parameters:
url('^(?P\d{6})$', RedirectView.as_view(url='/entry/%(number)s')),
Why is there an 's' ? I could not find documentation on this.
Thanks
François
