I know there is already a similar question but the answers to that didn't work for me
I'm working with Genexus 16U11 and I have a panel with an image variable (called &sourceImage) with control type as "SD Image Annotation". I need to send this image to the server, in a specific folder. According the documentation if I call a procedure using the image as variable this should go on the server but it's not working. I can't find the image anywhere, I searched also in the PublicTempStorage directory, in the procedure is as the variable is empty.
I tried also to convert the image in base64 to send it as longvarchar to the procedure
&blob = &sourceImage.GetAnnotatedImage()
&longvarchar = ToBase64(&blob)
but in this way I can only get this string ZmlsZTovLy8vc3RvcmFnZS9lbXVsYXRlZC8wL0FuZHJvaWQvZGF0YS9jb20uYXJ0ZWNoLnJpY2hpZXN0YXBlcm1lc3NpMTZ1MTEuc2Zpcm1hL2ZpbGVzL3RyYW5zZm9ybWF0aW9ucy8yMDIyLTAzLTE4LS0xNC00My0yNi02MTQ2NDcyMTA5MjM5NDU3NzgzODAxLnBuZw==
that is the path of the file

I tried with file variable, blob, image, extra images, method fromUrl, nothing is working.
What am I doing wrong?
To upload the image to the server you need to call the procedure in the server (Connectivity=Online).
Then the image variable will be send to the server and you can save, copy, etc. there.
For example, save in a Transaction with a code like this:
Call in the panel:
Composite
&resultImage = &ImageA.GetAnnotatedImage()
procSaveImage(&resultImage)
EndComposite
Procedure online:
&TrnData = new()
&TrnData.TrnDataImage = &parmImage
&TrnData.Insert()
if &TrnData.Success()

With a Genexus procedure, setting the call protocol to Http and the output_file rule, you can create a report and show to the user a pdf, basic Genexus tool. My problem is that I can't set the name of this pdf, it ignores the parameter of the output_file rule and if I try to save the pdf manually, it's named as the name of the procedure.
Can I set the name of the pdf somehow? Better if I can send it as parameter
Add this code to the procedure.
// &DocumentFriendlyName is varchar(100)
&HttpResponse.AddHeader(!"Content-Type", !"application/pdf")
&HttpResponse.AddHeader(!"Content-Disposition", !"attachment;filename=" + &DocumentFriendlyName + !".pdf")
If you don't want to download the PDF directly, create the PDF on the server, then use a &Window object to show it.
&Window.Url = &DownloadPdfUrl
&Window.Open()
If you add the rule:
Output_file(&FileName, 'PDF');
It does not generate the file with the value of the variable &FileName?
I sucessfully created a premirror for our yocto builds on an Azure Storage Blob,
that works if I set the access level to "Blob (Anonymous read).."
Now I wanted to keep the blob completely private, and access only via SAS Tokens.
SAS_TOKEN = "?sv=2019-12-12&ss=bf&srt=co&sp=rdl&se=2020-08-19T17:38:27Z&st=2020-08-19T09:38:27Z&spr=https&sig=abcdef_TEST"
INHERIT += "own-mirrors"
SOURCE_MIRROR_URL = "https://somewhere.blob.core.windows.net/our-mirror/downloads/BASENAME${SAS_TOKEN}"
BB_FETCH_PREMIRRORONLY = "1"
In general this works, but yocto (or to be exact the bitbake fetch module) will try then try to fetch from https://somewhere.blob.core.windows.net/our-mirror/downloads/bash-5.0.tar.gz%3Fsv%3D2019-12-12%26ss%3Dbf%26srt%3Dco%26sp%3Drdl%26se%3D2020-08-19T17%3A38%3A27Z%26st%3D2020-08-19T09%3A38%3A27Z%26spr%3Dhttps%26sig%3Dabcdef_TEST/bash-5.0.tar.gz
Which also encodes the special characters for the parameters and of course the fetch fill fail.
Did anybody has solved this or similar issues already?
Or is it possible to patch files inside the poky layer (namely in ./layers/poky/bitbake/lib/bb/fetch2) without changing them, so I can roll my on encodeurl function there?
I'm new to use Testcomplete , i'm using javascripts to automate my code, below are sample script ( converted one recorded first then converted into jscript) and in this scripts what i observe that TestComplete identified and captured the object element by using complete web url path not on only object specific .
efunction Test_Login {var UserName, Password, TestEnv;UserName = "XYZ";Pwd = "XYZXYZ";TestEnv = "https://test.Env.com/";Browsers.Item(btChrome).Run("TestEnv",1);Aliases.browser.pageTestenvCom.formFrmlogincomponent.textboxUsername.SetText("UserName");Aliases.browser.pageTestenvCom.formFrmlogincomponent.passwordboxPassword.SetText("Pwd");Aliases.browser.pageTestenvCom.formFrmlogincomponent.buttonLogin.ClickButton();}e
what i means lets see below example of login page
thank you
Whenever we record any Test case in Test-Complete, it stores all the object in the Naming Repository and then access the same.
This helps test-complete in easily recognisation of object and can improve the speed of test-case, in case there are multiple objects visible on screen

I have a models.ImageField which I sometimes populate with the corresponding forms.ImageField. Sometimes, instead of using a form, I want to update the image field with an ajax POST. I am passing both the image filename, and the image content (base64 encoded), so that in my api view I have everything I need. But I do not really know how to do this manually, since I have always relied in form processing, which automatically populates the models.ImageField.
How can I manually populate the models.ImageField having the filename and the file contents?
EDIT
I have reached the following status:
instance.image.save(file_name, File(StringIO(data)))
instance.save()
And this is updating the file reference, using the right value configured in upload_to in the ImageField.
But it is not saving the image. I would have imagined that the first .save call would:
Generate a file name in the configured storage
Save the file contents to the selected file, including handling of any kind of storage configured for this ImageField (local FS, Amazon S3, or whatever)
Update the reference to the file in the ImageField
And the second .save would actually save the updated instance to the database.
What am I doing wrong? How can I make sure that the new image content is actually written to disk, in the automatically generated file name?
EDIT2
I have a very unsatisfactory workaround, which is working but is very limited. This illustrates the problems that using the ImageField directly would solve:
# TODO: workaround because I do not yet know how to correctly populate the ImageField
# This is very limited because:
# - only uses local filesystem (no AWS S3, ...)
# - does not provide the advance splitting provided by upload_to
local_file = os.path.join(settings.MEDIA_ROOT, file_name)
with open(local_file, 'wb') as f:
f.write(data)
instance.image = file_name
instance.save()
EDIT3
So, after some more playing around I have discovered that my first implementation is doing the right thing, but silently failing if the passed data has the wrong format (I was mistakingly passing the base64 instead of the decoded data). I'll post this as a solution
Just save the file and the instance:
instance.image.save(file_name, File(StringIO(data)))
instance.save()
No idea where the docs for this usecase are.
You can use InMemoryUploadedFile directly to save data:
file = cStringIO.StringIO(base64.b64decode(request.POST['file']))
image = InMemoryUploadedFile(file,
field_name='file',
name=request.POST['name'],
content_type="image/jpeg",
size=sys.getsizeof(file),
charset=None)
instance.image = image
instance.save()
I am new to the Google App Engine and I am trying to use the Blobstore to store images that I want to display later on.
The image storage works fine. Now I want to dynamically change some images in my html code. Therefore I need a method of getting the images out of the blobstore and passing them. I am using Python. I found the get_serving_url-command, which seemed to be the perfect fit. Sadly, this causes an Error and I seem to be unable to fix it.
My basic code looks like this:
blob_key = "yu343mQ7kT4344N434ewQ=="
if blob_key:
blob_info = blobstore.get(blob_key)
if blob_info:
img = images.Image(blob_key=blob_key)
url = images.get_serving_url(blob_key)
...
Everytime the function gets called, I get the following Error in my Log Console.
File "C:\Program Files
(x86)\Google\google_appengine\google\appengine\ext\remote_api\remote_api_stub.py",
line 234, in _MakeRealSyncCall
raise pickle.loads(response_pb.exception())
AttributeError: 'ImagesNotImplementedServiceStub' object has no
attribute 'THREADSAFE'
I have no idea how to fix it or if I am doing something terribly wrong.
I am very grateful for your support! Thank you in advance!
Have a nice day
You probably need an instance of BlobKey so if you are getting blob_info successfully try:
img = images.Image(blob_key=blob_info.key())
url = images.get_serving_url(blob_info.key())
