python - Rendering JSON output on Flask Bootstrap Page -


i trying display json file flask html page.

flask

@app.route("/analysis") def analysis():     data = pd.read_csv('static/uploads/' + global_file.filename)     temp_json = data.to_json(orient='records')     json_df = json.loads(temp_json)     list = json_df     return render_template('results.html', summary = json.dumps(list))

html

<div class="results">     <table>         {% key in summary %}             {{ key.name }}         {% endfor %}     </table>   </div>

json

name    age class   marks       12     6    32 b       13     6    32 c       14     6    43 d       12     6    54 e       13     6    23

i getting blank page ouptut. want display pretty table on page.

the reason happens convert json object string using json.dumps iterate through string (character character) , try access name attribute. if leave out .name, indeed see every character printed out after eachother.

to fix should provide template actual object: list of dicts. so:

@app.route("/analysis") def analysis():     data = pd.read_csv('static/uploads/' + global_file.filename)     temp_json = data.to_json(orient='records')     json_df = json.loads(temp_json)     return render_template('results.html', summary = json_df)

then still there won't actual table, because in template there no tr or td elements. if fix that:

<div class="results">      <table>          {% item in summary %}              <tr><td>              {{ item['name'] }}              </td></tr>          {% endfor %}      </table> </div>

you see actual table.

edit: conversions inside of analyse method bit superfluous, maybe shortened code post here?

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
