legacyhalos-web's Issues

Default form values stopped working

Form values in list.html stopped appearing as default value, and disappear when user clicks search, instead of remaining in search box. This functionality worked before pagination was added.

legacyhalos-web/legacyhalos_web/templates/list.html

Lines 19 to 37 in 9bcbdc9

 <td><input id="id" name="mem_match_id" type="number" value="{{ filter.form.mem_match_id.value}}"/></td> 

 </tr> 

 <p></p> 

 <tr> 

 <th><label for="ralo">RA low:</label></th> 

 <td><input id="ralo" name="ra__gt" step="0.01" type="number" value="{{ filter.form.ra__gt.value|default_if_none:'100'}}"/></td> 

 </tr> 

 <tr> 

 <th><label for="rahi">RA high:</label></th> 

 <td><input id="rahi" name="ra__lt" step="0.01" type="number" value="{{ filter.form.ra__lt.value|default_if_none:'200'}}"/></td> 

 </tr> 

 <p></p> 

 <tr> 

 <th><label for="declo">Dec low:</label></th> 

 <td><input id="declo" name="dec__gt" step="0.01" type="number" value="{{ filter.form.dec__gt.value|default_if_none:'0' }}"/></td> 

 </tr> 

 <tr> 

 <th><label for="dechi">Dec high:</label></th> 

 <td><input id="dechi" name="dec__lt" step="0.01" type="number" value="{{ filter.form.dec__lt.value|default_if_none:'10' }}"/></td>

Add Downloadable Search Results feature

Add functionality for user to have option to download their search result.
May wish to download as .fits file like UnWise site. Give option to do so instead of loading table to browser.

Efficiency, where to store session

Currently in order to store the search results to a session, we serialize our queryset of objects using JSON then store to a session variable, which we configured to use the database, over cache or other options.
Setting session variable:

legacyhalos-web/legacyhalos_web/centrals/views.py

Line 16 in 9bcbdc9

req.session['results_list'] = serialize('json', cen_filtered, cls=LazyEncoder)

Serializing:

legacyhalos-web/legacyhalos_web/centrals/views.py

Lines 37 to 41 in 9bcbdc9

 class LazyEncoder(DjangoJSONEncoder): 

 def default(self, obj): 

 if instance(obj, Centrals): 

 return str(obj) 

 return super().default(obj)

Loading from session variable:

legacyhalos-web/legacyhalos_web/centrals/views.py

Line 27 in 9bcbdc9

cen_list = json.loads(req.session['results_list'])

Is this an efficient way to remember our query result to use it on individual central galaxy pages, in order to link to previous and next galaxy pages?
Is it better to store the session to cache, or to the database like we are currently?
Will this approach scale up once we have a larger data set?

Lines 23 to 33 in 23876fd

 def centrals(req): 

 index = int(req.GET.get('index')) 

 cen_list = pickle.loads(req.session['results_list']) 

 cen = cen_list[index-1:index][0] 

 prev_index = index - 1 

 if (prev_index == 0): 

 prev_index = len(cen_list) 

 next_index = index + 1 

 if (next_index > len(cen_list)): 

 next_index = 1 

 return render(req, 'centrals.html', {'cen_list': cen_list, 'index': index, 'cen': cen, 'next_index': next_index, 'prev_index': prev_index})

Use uniform data model throughout application

Sort on different properties

Make centrals page urls use mem_match_id for directly linking to page
