This file documents the contents of this module change Last update 4 sept. 2013 See the devel/ subdir for more devel-oriented doc. ==================== 1 minute howto * REQUIREMENTS is to have python + django (1.5.2) installed django ** should be straightforward ** see devel/django-install.txt in case of trouble $ apt-get install python-django $ apt-get install python-django-south * git clone git://git.onelab.eu/myslice.git -- or -- * git clone ssh://yourlogin@git.onelab.eu/git/myslice.git * edit/create myslice/myslice.ini and enter the details of your manifold backend $ apt-get install python-django-south * init django ** when django prompts for creating an admin account, create it and ** keep the username and password safe $ ./manage.py syncdb $ ./manage.py migrate * gather static files $ ./manage.py collectstatic -- or -- $ ./manage.py collectstatic --noinput -- or -- $ make static (which is a shorthand for cleaning up and run manage collectstatic --noinput) * gather templates files for now we still seem to rely on a make-based templates-collection process that creates templates/ $ make templates [$ make redo (each time when you pull, do that and restart the server)] ## Whenever doing a git pull the following operations are recommended: $ make static # will refresh static/ from all the pieces in the project $ make templates # same, for templates $ make redo-static # clears up (rm -rf) static/ first, then make static $ make redo-templates # ditto for templates $ make redo == make redo-static redo-templates * run a local server: $ ./manage.py runserver 0.0.0.0:8000 -- or -- my advice: $ devel/server-loop.sh when you just need to hit ^C yourself when your static files need to be refreshed - see below * use it from your browser (See more notes on using the development server below) * install dependencies $ pip install -r path/to/requirements/file.txt Note. not quite sure what this is about, I could not spot this file.. =====APACHE Config===== if are running apache please do: $ chown www-data:www-data /var/myslice-f4f otherwise you may get the following error: "DatabaseError: unable to open database file" ==================== Status *** Authentication *** Should be mostly fine Not quite sure if/how the user gets proper notifications when . his session has expired (i.e. his frontend is not logged into the backend any longer) . his credentials have expired (i.e. the uploaded credentials, e.g. SFA delegated cred) expired and she needs to run e.g. sfi myslice again Hard-coded accounts (from a very early stage) are gone *** Packaging *** I've done a very rough attempt at packaging for rpm. The logic seems about right but needs more work, in particular in terms of installing myslice.conf in the httpd conf.d directory. It seems like our app won't work on f14 as is because Django is only 1.3.1 on f14 Plan is to target f18 but I lack a test machine. Also of course I'll try to tackle debian/ubunti at some point. There also is a working packaging for debian(s) and ubuntu(s) that we use on an almost daily basis to upgrade manifold.pl.sophia.inria.fr ==================== Third party tools shipped: * jquery * datatables * spin * bootstrap Others are added as we build the system when they become needed Look in third-party/ for a more detailed list As a rule of thumb, please try to keep in mind that these will need to be upgraded over time I've tried to keep track of the version I picked and to have an easy upgrade path (depending on the way the original package is published) ==================== Contents: 1st level subdirs ========== code from git * myslice/ this is the django 'project', where to look for . settings.py . urls.py * manifold/ the code for dealing with queries, sending them to the backend, and offering the /manifold/proxy/ URL * unfold/ the code for building / rendering plugins * plugins/ the actual code for plugins * auth/ a django 'app' that deals with authentication; see especially auth.backend.MyCustomBackend for how to use a separate authentication system, as well as settings.py for how to enable it * ui/ provides building blocks for the UI, especially layouts (1 or 2 columns) as well as the topmenu widget + some global static files (css, js, images..) * portal/ this is where the first implementation of myslice, with complete user-management including registration, is taking place * trash/ rough/preliminary scaffolding views are in here as the name suggests this is temporary * insert_above: a third-party django app for adding on-the-fly mentions to css or js files that need to go in the header * third-party/ * third party javascript and css stuff (bootstrapfs, jquery, this kind of things) see more about that below too * devel: no code in there, only various notes and other scripts useful for developers ========== automatically generated * static/: (generated by collectstatic, see above, do not source-control) $ manage.py [ --noinput ] collectstatic * templates/ * myslice.sqlite3 this is where django stores its own stuff, as per settings.py ==================== conventions for templates & static files ==================== and NOTES on using the development server . first off, running manage.py runserver is provided by django as a development convenience but SHOULD NOT be used in production . second, when you do use it for developement purposes, please be aware that: .. the recommended layout for the various files and pieces (py, html, js and css) with django is e.g. plugins/quickfilter/___init__.py, plugins/quickfilter/templates/quickfilter.html, plugins/quickfilter/static/js/quickfilter.js plugins/quickfilter/static/css/quickfilter.css plugins/quickfilter/static/img/some-image.png .. the files actually used by the development server are the ones located in static/ templates/ you can and should use the following make targets to refresh the contents of these directories when running a developement server $ make static to refresh static/ $ make redo-static to clean up static/ and then refresh its contents $ make templates to refresh templates/ $ make redo-templates to clean up templates/ and then refresh its contents $ make redo equivalent to make redo-static redo-templates .. as far as possible, please make sure to use third-party to store any javascript tool or utility that your plugin depends upon also we have the convention that all material in third-party should be tagged with a version number, with a symlink pointing to the version being used, like this ~/git/myslice/third-party $ ls -ld spin* lrwxr-xr-x 1 parmentelat staff 10 Sep 6 17:55 spin -> spin-1.3.0 drwxr-xr-x 7 parmentelat staff 238 Sep 6 17:55 spin-1.2.8 drwxr-xr-x 7 parmentelat staff 238 Sep 6 17:55 spin-1.3.0 finally, as far as possible we keep track of the urls used to pull stuff in the first place so that upgrades are easier . third, be careful when importing third party material, to stay away from demo-oriented material e.g. at some point we were using demo_page.css and demo_table.css from the datatables demo and sample pages unfortunately these are not tailored for production use as they are setting styles on a very wide scope that breaks a lot of stuff, so please refrain from using these altogether ======== update django database to reflect changes in existing models without any migration system (e.g., south) ========= # older version $python manage.py reset #Django 1.5.1 or later $python manage.py flush This will update the database tables for your app, but will completely destroy any data that existed in those tables. If the changes you made to your app model do not break your old schema (for instance, you added a new, optional field) you can simply dump the data before and reload it afterwards, like so: $python manage.py syncdb $python manage.py dumpdata > temp_data.json $python manage.py flush $python manage.py loaddata temp_data.json If your changes break your old schema this won't work - in which case tools like south or django evolution are great. Add a new model to the DB $python manage.py schemamigration --auto $python manage.py migrate ======== update django database to reflect changes in existing models with migration system (e.g., south) ========= As south is already installed , you just have to do: # ./manage.py schemamigration portal --initial # sqlite3 /var/unfold/unfold.sqlite3 sqlite> DROP TABLE "portal_institution"; sqlite> DROP TABLE "portal_pendinguser"; sqlite> DROP TABLE "portal_pendingauthority"; sqlite> DROP TABLE "portal_pendingslice"; sqlite> .quit # ./manage.py migrate portal
