php - Yii2 GridView widget not displaying data -

-

I have a scene where I am trying to output data: 

  resonates Gridview:: Widgets (['dataProvider' = & gt; $ DATAprader, 'Columns' => [['' Labels '= & gt;' Contact ',' Attribute '=>' Client Contract ',' Value '= & gt; Client contractual contact ASHML', 'format' = & gt; 'raw'],   
 ... etc. The problem is that no area is displayed Even if they are in the database and the mod Should be received by:  
  public function getContactAsHTML () {return Html :: a ($ this- & gt; contact, ['contact / view /', 'id' = & gt; ; $ This-> ID])}}   
 ... etc. Is this a problem in my thoughts or models?  
   
 
 
 I think it's fixed, the problem was actually in the controller, where 'datapriver' Was being specified in the use. I have decided to do a 'hike' for a while now, where I sponsor a new data outside of the real scene, and now I can get it to display the data.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

java - Session timeout does't work vaadin -

I am developing a vaadin web application and I have added the following snippet of code in my web.xml. & lt; Session-Config & gt; & Lt; Session timeout & gt; 30 & lt; / Session timeout & gt; & Lt; / Session-config & gt; Now I have noticed after 30 minutes that my users are capable of using appllication and I do not want this. I read something about this problem on the book Wadin but I do not believe in anything. From the Wadin book: The session expires after user deactivation In the normal servlet operation, the session time defines the allowed time of inactivity After which the server should clear the session. Inactivity is measured by the last server request. Different servicelists use different default for container timeouts, such as 30 minutes for Apache Tomcat. You can set the timeout with: In a web.xml: & lt; Session-config & gt; & Lt; Session timeout & gt; 30 & lt; / Session timeout & gt; & Lt; / S...
