Hi all,

We are eventually trying to put our codes into omeroweb/searcher.

0.
if we want create "searcher" folder under "omeroweb", we need to modify the setting.py for INSTALLED APP to include omeroweb.searcher, right?

1.
And also in that new folder, we need to write
__init__.py,
urls.py
views.py

is there any restrictions with these files? If there is basic sample files for them, please send me.

2. About the inheritance of the default template pages (such as base.html) .
The basic template files are under /omeroweb/webclient/templates/...

Can you explain how to use those basic template files from an app under /omeroweb/searcher/ ?
I'm asking this question because it looks like the functions in template_loader can only load those template in the same folder.
For example, in the views.py under omeroweb/webclient (I'm playing with omero 4.2.1), the following line

template = "webclient/login.html"

refers to the login.html file under /omeroweb/webclient/templates/webclient/login.html

If I want to use the same login.html file from my own app under /omeroweb/searcher/views.py, could you tell me how to do?


3.
A technically general question about javascript.
We added a button on a default omero web page and when you click it, it executes a javascript function like the following,

Code: Select all

function relevance_feedback_entireDB() {
    if (!isCheckedById("image")) {//&& !isCheckedById("dataset") && !isCheckedById("plate")) {
        alert ("Please select at least one image. Currently you cannot add other objects to basket.");
    } else {
        var productArray = $("input[type='checkbox']:checked");
        var productListQuery = "";
        var datasetID = "0";
        var featureset = "SLF34";
        var numretrieve = "10";

        if (productArray.length > 0 ) {
            productArray.each(function() {
                if(this.checked) {
                    productListQuery += this.id + ",";
                }
            });
        } else {
            productListQuery += productArray.id + ",";
        }
       
        URL = productListQuery+'/'+datasetID+'/'+featureset+'/'+ numretrieve+'/';
          window.location = 'http://omepslid.compbio.cs.cmu.edu/webclient/relevance/' + URL + '';
    }
   
    return false;
}


and it will call our app under /webclient/relevance/.
But, the line at the bottom

Code: Select all

window.location = 'http://omepslid.compbio.cs.cmu.edu/webclient/relevance/' + URL + '';

should be definitely modified to make this function work on any server.
Could you tell me how to do this? (there could be a global variable that directs to the url of the local server)



Best,

Hi BK,

Most of your questions are answered on the "How to create an app" page that I'm currently editing

http://trac.openmicroscopy.org.uk/ome/w ... /CreateApp

Briefly:

0. Correct - You have to add "searcher" to the INSTALLED APP list in settings.py and also add it to the urls lists in omeroweb/urls.py (should be obvious from the other examples there).

1. For very basic samples, see the link above.

2. I think you should be able to use "webclient/login.html" from another app. I haven't tried this, but I think the reason that the templates are in folders called E.g. webclient/templates/webclient/login.html means that the second "webclient" folder in that path can be used to refer to webclient templates from other apps. See https://docs.djangoproject.com/en/dev/r ... -templates

You can also "extend" templates between apps (see the index.html example code at the above link).

3. At a guess, does this work?

Code: Select all

window.location = '/webclient/relevance/' + URL + '';


The other thing you can try, if the javascript is in a Django html page (not in static media), then you can use Django template to add links into the javascript. This can make the javascript a little ugly but allows you to use "named" Django urls and could solve your problem:
E.g.

Code: Select all

window.location = "{% url relevance URL %}"';


Have a look at webtest/index.html for some examples of this technique to generate thumbnail urls from webgateway.

NB: If your app is "relevance" then the url will not contain "webclient"? Like this?

Code: Select all

http://omepslid.compbio.cs.cmu.edu/relevance/


Will.
