It works pretty well the way i described, but I understand the
problem. <br>
even if there is no perfomance decrease yet it is probably because
i'm in the developpement stage with few users, not in production.<br>
When you say it slows down the API, is it because it produces many
more SQL requests on the DB ? <br>
(ie Having a first result from the db, then making new queries to
obtain the user-resource-permision value)<br>
Can a solution be to build a <a
href="https://docs.djangoproject.com/en/1.8/topics/db/sql/">raw
SQL query</a> a bit more complex ? <br>
create a special view with a join between user, resource and perms
then request it... only reading it, never write.<br>
<br>
Thanks<br>

<div dir="ltr">Hi Hugo,
<div>the "easies" way would be to create a dedicated API for non
permitted resources that is used in a separate tab in the
search pages dedicate to resources that are in GeoNode but the
user does not have the permission to view.</div>
<div>The reasons behind that are:</div>
<div>- The current api, for performances purpose, do not loop
over each result in any way, they just take the data from the
db, apply filters, then send to the client. If you have to
distinguish between permitted and not permitted then you have
to add back the post processing that will slow down the API.
Better have a dedicated API to this task.</div>
<div>- In the client side, there's Angular.js that renders the
resources and even if the angular tags look the same as the
django ones {{tag}} they are actually rendered by Angular. The
_resourcebase_snippet works this way, so you cannot use django
template tags in there.</div>
<div><br>
</div>
<div>If you create a separate tab you can use the same logic
both on the client and on the server with just a different api
endpoint at the price of not having the results mixed in the
same list.</div>
<div><br>
</div>
<div>If you decide to activate the API post processing
(dehidratation cycle) then try to keep it as light as possible
otherwise the performances will drop especially if you
visualize many data all together.</div>

everyone<br>
I've modified geonode behavior to make every user (logged or
not) to view the complete list of the resources stored in
geoserver and geonode store, and the ability to download the
metadatas.<br>
Then I add some restrictions to allow only a few users to
explore it:<br>
what I mean by "exploring it" is displaying the geoexplorer
frame for layers and giving auth to download it.<br>
the aim is to show users the whole catalog first, and e-mail
the Point of Contact if a resource cannot be retrivied
because of restriction.<br>
<br>
To improve the user experience I want to make a distinction
on resource lists:<br>
when a resource is only "viewable" (ie displayed in the list
but with no permision to download it),<br>
it displays a "restricted access" message in the
resource-base-snippet template, near the MD infos and
thumbnail.<br>
So the user will be aware that he has no right to retrieve
it directly without contact the PoC.<br>
<br>
To do that I modify JSON answer from the server when we ask
him to get the list of available resources:<br>
the answer is built in create_response method from
CommonModelApi in api module.<br>
We can see that a single resource retrieved from the db is
sent back with some Metadata-fields.<br>
I just want to put a single boolean that will tell if user
has the right to download it.<br>
<br>
I have already written the short function to get this
boolean, but as a template tag, used in the resources detail
templates.<br>
So i 'll have to write an other function to use it the
python module.<br>
It will produce duplicate code.<br>
<br>
Do you have some advice to do it in a better way ?<br>
<br>
Thanks,<br>

Hello,<br>
<br>
I am following the Customizing the geonode instructions
and looking for the<br>
template files to copy to etc/geonode/templates<br>
<br>
e.g.<br>
<br>
/var/lib/geonode/src/GeoNodePy/geonode/templates/index.html<br>
<br>
However the directory /var/lib/geonode/ doesn't exist.<br>
<br>
<br>
Where can I find a copy of these templates?<br>
<br>
I am using v*ersion 2.4b25* of geonode.<br>
<br>
Thank you.<br>
<br>
Will<br>

Hi, in the map view, I have tried to query a single

Things I would check (in this order):<br>
* response to the getfeatureinfo request using your
browser debug toolbar<br>
* geoserver log<br>
* try the query in postgis and check it using EXPLAIN<br>
