pwell many use pip package manager for their install purpose not my favoritebr
to install django through pip you do something likep
precodepip install django
codepre
pit will install django in a path which is not accessible by nonroot usersbr
so you must first add the installation place for itp
precodepip install django installoptionprefixsomeplacewehaveaccessto django
codepre
pthis codesomeplacewehaveaccesstocode can be codehomeusercode directorybr
now login to python and do the importp
precodeimport django

importerror no module named django
codepre
pwhat are we doing wrongp
h3pythonpathh3
pwell as long as you have not installed django in pythonpath python doesnt know where to import the module
do this two stepsp
blockquote
pbash p
blockquote
precodeecho pythonpath
codepre
blockquote
ppythonp
blockquote
precodeimport sys

codepre
pwell syspath show the path of packages locations installed in python
and pythonpath is emptyp
pthe only thing you have to do is to add the path of django egg file to pythonpath
for example in mine itsbr
codeusrlocallibpython27distpackagesdjango19py27eggcodebr
to add it to pythonpath do this p
blockquote
pbash p
blockquote
pcodeexport pythonpathegg pathcodebr
which egg path} is the location of your django egg.<br>
<strong>what about django-admin</strong>?<br>
well you have to run it from the place that django has set it up in somewhere it has been installed called <code>bin</code>
for that you can add the path of that bin (think it might be ~/bin or any_place_you_installed/bin) to $path...<br>
just like pythonpath we do:</p>
<pre><code>export path=$path:~/bin
</code></pre>
<p><em>attention</em> >> : after $path is essential!!! to know why do a: <code>echo $path</code><br>
<em>attention</em> >> ~/bin must be django bin directory so pay attention to that.</p>
<h2>installing django through source</h2>
<p>oh my god that's my <strong>favorite</strong>.
there is nothing difference with the thing up there just insted pip use setup.py...</p>
<p>for that you must have setuptools installed... (i think pip will install that itself if pip raises error for setuptools you must do the whole thing i told up there for django for setuptools too.)</p>
<p>after you installed setuptools you must do this:</p>
<pre><code>./setup.py install --prefix=$path_you_desire
</code></pre>
<p>the rest is the same...</p>

how do i make a scatter plot with these data | pto be able to fully determine if your way of storing data is correct you should consider how you use it if youre using it only want to use it for plotting as described here then for the sake of the simplicity you can just use three 1d arrays if however you wish to achieve tighter structure you might consider using a 2d array with a hrefhttpdocsscipyorgdocnumpyreferencearraysdtypeshtml relnofollowcustom dtypeap
phaving this in mind you can easily create a 2d scatter plot with different colors where exact color is determined by the value associated with each pair letter numberp
precodeimport numpy as np
from matplotlib import pyplot as plt
from matplotlib import cm
you might note that in this simple case using numpy for creating array
was actually unnecessary as simple lists would suffice
letters nparraya a a b b b
numbers nparray1 2 3 1 2 3
values nparray1 2 3 15 35 45
items lenletters
x and y should be numbers so we first feed it some integers
parameter c defines color values and cmap defines color mappings
pltscatterxrangeitems numbers cvalues cmapcmjet
now that data is created we can reset xticks

saleor django apache modwsgi will not serve staticadmin | pi did not understand the documentation on a hrefhttpsdocsdjangoprojectcomen19howtodeploymentwsgimodwsgiservingtheadminfiles relnofollowserving the admin filesa or a hrefhttpsdocsdjangoprojectcomen19refcontribstaticfilesdjangoadmincollectstatic relnofollowdjangoadmin collectstaticap
pthe documentation for serving the admin files indicated that if one has djangocontribstaticfiles enabled in the installedapps portion of settingspy then it is recommended the staticfilesdirs list in settingspy shall contain the paths to the static directory djangocontribadminstaticadmin provided by django for its development serverp
pone is told to use the collectstatic management command which will physically copy the files to a static directory in what you will configure as serverroot in your sitenameconf file for apache to servep

pwhich then proceeds to magically copy what i need i hope into my projectstatic directoryp
pmy noob mistake was not reading a hrefhttpsdocsdjangoprojectcomen19refdjangoadmin relnofollow>django-admin and manage.py</a> first, thus discovering that the convenience script has a convenience script. <em>rimshot</em></p>
<p>another bit of confusion (for me, anyway) is the assertion that one should not serve static files from the "app" or the "admin app". a simpler way for me to think about it is: "one must run a script that appears either wrap or replicate rsync, thus copying static files from myapp/static and ~/project/venv/lib/python2.7/contrib/admin so that apache will not be able to play silly buggers with important files". this does not mean that one does not put a path to /static/ in the sitename.conf file. there is no magic here, just copying static files.</p>

why django and python mysqldb have one cursor per database | pone cursor per database is not necessarily preferable its just the default behaviorp
pthe rationale is that different databases are more often than not on different servers use different engines andor need different initialization options otherwise why should you be using different databases in the first placep
pin your case if your two databases are just namespaces of tables what should be called schemas in sql jargon but reside on the same mysql instance then by all means use a single connection how to configure django to do so is actually an altogether different questionp
pyou are also right that a single connection is better than two if you only have a single thread and dont actually need two database workers at the same timep

what do you mean by dispatch function and forwarding function in boostpython | pthe dispatch function is the implementation which switches on the derived class type to find out which implementation of a virtual function should execute like a pure virtual function the forwarding function seems to refer to the default base class implementation of the virtual functionp
pi too find this terminology a bit confusing but its only used in passing in the boost documentation and i dont think its very important in the grand scheme of things try not to get hung up on itp

pof course if codestrisprintablecode isnt exactly the definition you want you can write a different function note that its a very different set from whats in codestringprintablecodebesides handling nonascii printable and nonprintable characters it also considers codencode codercode codetcode codex0bcode and codex0ccode as nonprintablep
