I recently installed django-debug-toolbar. The Alexa plugin is working and I can see the tabs associated with the site. However, nothing shows up in the SQL tab even though I explicitly executed the SQL query (as I see it in the admin):

Any help with this shortcoming would be great…
Edit:Based on the method, I decided to post how I processI give my display functions:
def func1(query, var1): request = request. filter(var__icontains = var1) consultationdef func2(request, var2): = query query.filter(var__icontains=var2) consultationdef parse(**kwargs): Number Based on logic call us func1 and func2 make a requesttype of protection (request, template = "display.html"): # Process request problem = parse(request.GET.items()) Return concept, rendering(query, "elements": list(query))How to view SQL query in Django?
You can use django debug_toolbar to view the sql query. Step by step guide to use debug_toolbar: edit your settings.py file and add debug_toolbar to your installed applications, this should be added in what will be “django.contrib.staticfiles”. Also add debug_toolbar to the middleware.
Hi, I recently upgraded to the latest version of the Django Debug Alexa Toolbar (3.1.1) and am facing a major performance issue.
When the view is executing every “huge” text SQL query (in the form), the display in the toolbar is very, very slow.
The view only takes about 1 second to render, while the Alexa tool on my computer takes about 58-59 seconds.
The problem should be solved somehow by commenting out stack.In enable_grouping() process parse_sql from panels/sql/utils.py ( line 34).
[EXAMPLE] Here is the request type causing the problem:
I know what it’s about The lemma is related to the sqlparse package, but disabling the package (or optional) does not guarantee much difference in rendering results.
SELECT ••• FROM "sample" LEFT OUTER JOIN "sample_parents" ON ("sample".."id" = "sample_parents".."from_sample_id") INNER "sample_parents" join T4 ON ("sample".."id" = T4."to_sample_id") WHERE T4."from_sample_id" IN (856, 860, 858, 862, 900, 1154, 1155, 1156, [... over 2000 numbers...], 29583) GROUP BY ("Probe_Parents"..from_Probe_ID"), "Probe.."ID"Project Description
Django’s debug toolbar is a custom set of panels that experts say display different panels.Debug information about the last request/response and on click will be displayedLearn more about the content of these panels.
If you have ideas for other sections, please let us know.
Settings
-
Add debug_toolbar to provide the path to Python.
-
Add the following middleware, which will become your project’s settings.py file:
'debug_toolbar.middleware.Into debugtoolbarmiddleware',
The synchronization middleware allows you to instantiate each panel on demand.Rendering will be done on the response.
The sequence MIDDLEWARE_CLASSES is: Debug toolbar middlewaremust come after any other middleware that the experts think encodes the content of the response(for example, promGZip middleware).
Note. The debug toolbar is only displayed if its MIME type isThe response is either text/html with application/xhtml+xml and containsclosing
