java - nullSafeGet in Hibernate 4 -


I'm upgrading to Hibernate 3 HubNet 4.1.

 I think that hibernate in 4  nullSafeGet ()  and  Nlsafset ( ) . That's why I have to use these methods to use new parameters, and anyway, in the customized inequality, the session supplement must be ignored.  
  findDocuments ()  Basically query documents from the document table,  Document.hmb.xml  is not a custom type in any area of ​​my Why the puzzle is called  CustomType.nullSafeGet () ? In the document. H.B.M.L.L. In, only one is suspicious, but I'm not sure that the same error gets after changing the type of type to "blob".  
  & lt; Property name = "image" column = "picture" type = "org.springframework.orm.hibernate3.support.BlobByteArrayType" />   
 Can you please help?   
 
 
 Resolve my question by changing " org.springframework.orm.hibernate3.support.BlobByteArrayType Is done  from " materialized_blob .  
  & lt; Property name = "picture" column = "picture" type = "physical content" />   
 it seems that the Spring Formation call  Hibernate 3 customType.Java  is  Hibernate fights with customType.Java . One lesson learned, when Hibernate 3 to 4 is upgraded, the Blob column is required to be used as the " physical / bob " type, which is a simpler solution than Hibernate 3 , Spring  LowBandler  within the session

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...
