typo3 - Is it possible to write a specific query in typoscript -

-

My question may look insignificant, sorry if it is! I'm currently learning typo3 and typoscript. I want to create a template with a dynamic background image. This image is stored in a directory. I would like to get the image name from the table tt_content However, the way it works makes me a little confused And I do not know that it's okay to take mine.

The code looks like this: 

  20 = content 20.table = tt_content 20.select {where = pid = 79} 20. header image path = COA 20. header imagepath {10 = Text 10.stdWrap.field = image 10.stdWrap.wrap = & lt; Div class = "background-media" style = "background-image: url ('|'); background-repeat: repeat any; background-shape: cover; background-attachment: fixed; background-position: 50%;" Data-start = "background-position: 50% 50%" data -70-up-down = "background-condition: 50% 70%" & gt; & Lt; / Div & gt; }   
 I would like to store information about the image in a variable (Divya part in code) and put it in my template. The template section of my code looks like this:  
  & lt; F: format.raw & gt; {Headimage} & lt; / F: format.raw & gt;   
 or  
  & lt; F: cObject typoscriptObjectPath = "headerimage" />   
 So my question is, am I choosing things from the database and am storing a variable right and the way I am telling them right in the template? Should work upwards but I have some minor errors, is it a good practice or should I work differently?  
 Kind regards  
 etc   
 
 
 Your snippet work Because your structure is very wrong.  
 ON  
  20.Addressor imagepath = COA   
 You try to make someone new on one.  
  20 = CONTENT   
 This will not work.  
 But in the content object there is a property called render oz.  
 See the following example:  
 Uninstalled  
 Try it like this:  
  lib.headerImagePath = CONTENT lib. HeaderImagePath {# First you need the table, call content = tt_content {# Add your callpost # In this example, I store my header image in colombo 9 where = colPos = 9 # PID from the current field or your own Own # pidInList = 123 pidInList.field = uid languageField = sys_language_uid} Render Obje = COA render oz {# FILES objects in TYPO3 6.x 10 = file pelted in 10 {# Set a reference to let the file go to the object, where we get the image reference {table = tt_content uid.field = uid fieldName = image} # Make sure we can only get the maximum image in the set Max_tems = 1 renderObj = COA renderObj {# We need the URL only, not the whole image, so we do not need an IMG_RESOURCE and an IMAGE object 10 = IMGSsers 10 {stdWrap {wrap = & lt; Div class = "background-media" style = "background-image: url ('|'); background-repeat: no-repeater; background-shaped: cover; background-attachment: fixed; background-position: 50%;" Data-start = "background-position: 50% 50%" data -70-up-down = "background-condition: 50% 70%" & gt; & Lt; / Div & gt; Required = 1} # Import the file from the current object # and treat the ID as a reference (TIPO3 File Abstraction Layer) file {import.data = file: current: uid treatIdAsReference = 1}}}}}}}   
 See also this example:  
 Get header images from Media Elements directly in those page properties:

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...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
