Hi,
I have a chart which I generate on the fly.
Basically, I have hard linked an image. The image src contains GET
parameters, which is used to generate the chart image via matplotlib.
The resultant image is returned back as 'Content-Type' = 'image/png',
and thus the chart is displayed.
i.e. <img src='/chart?key1=field1&key2=field2' /> is there in
HTML - created using templates. The parameters key1, key2, field1,
field2 etc are used to create the image.
Now, this was working perfectly till now. Now, I need to create a
huge chart with lot of keys and fields. But, when I tried the same
mechanism, it failed because it is above the maximum characters
supported by GET. Even though I could not find any specific spec which
mentioned the max char limit, I understand that many browsers support
very less characters only ~300.
In such a case, how can I create the chart on the fly? Is there a
way to send the data as POST while hardlinking? Since I am getting the
values and generating the links using templates, I cannot think of too
many options. What si the usual mechanism used by fellow Djangoites?
Any help would be much appreciated. Thank you all in advance.
