c# - Entity Framework multiple search with empty variables? -


I want to find many and want to get results. I send this function devicename user alarm When these variables are filled, then it works. But when they are empty, it is not so. I can only fill the devicename variable for example; 

  devicename = "test"; Alarm = ""; User = "";   
 Sometimes I can fill up the  devicename   user , sometimes I  devicename   Alarms  .. I can not get any data from my code. I need help Here is my code:  
  list & lt; Activity log & gt; List = db.ActivityLog.Where (C => c.Devices.devName.ToLower (). Includes (devicename.ToLower ()). Where (c = & gt; c.users.uName.ToLower (). Contains (user. Taylor ()). Where (C => c.AlarmCodes.aName.ToLower (). Includes (alarm. ToLower ()). Order By (C => CDATime). Take Skip (Skip) (pageSize) .ToList ();    
 
 
  list & lt; activity log & gt; list = Db.ActivityLog.Where (C => devicename == "" || c.Devices.devName.ToLower () contains it (devicename.ToLower ()). Where (C => User == "C" (C => Alarm == "" || c.AlarmCodes.aName.ToLower (). It contains (alarm. ToLower ()). OrderBe (C = & gt; CDATime). Leaving (Skip ). Move (Page Size). St ();   
 And as Mihai suggested that you can add to all the stories.  the

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example.

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
