linq - IQueriable() to ListAsync() conversion issue due to filter on list inside a list -


i have issue filtering list inside list on async method.

private async task<list<userlist>> getasynclist(string query) {       var result = getuserlist.where(x =>             x.firstname.toupper().contains(query.toupper())                                                                                           || x.lastname.toupper().contains(query.toupper())                                                                                        || x.emailid.toupper().contains(query.toupper())                                **|| x.userrole.any(a => a.toupper().contains(query.toupper()))**);             return await result.tolistasync(); }

getting below exception

expression of type 'system.collections.generic.iasyncenumerable1[system.string]' cannot used parameter of type 'system.collections.generic.ienumerable1[system.string]' of method 'system.collections.generic.list1[system.string] tolist[string](system.collections.generic.ienumerable1[system.string])' parameter name: arg0

kindly on this!

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...
