I have an ADF pipeline moving a file to a blob storage. I am trying to pass the processed file as a parameter of my web activity so that I can use it as an email attachment. I am successfully passing the following parameters:
{
"Title":"Error File Received From MOE",
"Message": "This is a test message.",
"DataFactoryName":"#{pipeline().DataFactory}",
"PipelineName":"#{pipeline().Pipeline}",
"PipelineRunId":"#{pipeline().RunId}",
"Time":"#{utcnow()}",
"File":????????????????????????????
}
But, how should I specify the path to the file I just processed within the same pipeline?
Any help would be greatly appreciated,
Thanks

I'm copying data to output container. My current assumption is to upload a file a day, and then use two GetMetadata activities to get the lastModified attribute of the file to filter out the name of the most recently uploaded file.
Get Child items in Get Metadata1 activity.
Then in Foreach activity, get child items via dynamic content #activity('Get Metadata1').output.childItems
Inside Foreach activity, in Get Metadata2 activity, specify the json4 dataset to the output container.
Enter dynamic content #item().name to foreach the filename list.
In If condition activity, using #equals(dayOfMonth(activity('Get Metadata2').output.lastModified),dayOfMonth(utcnow())) to determine whether the date the file was uploaded is today.
In true activity, add dynamic content #concat('https://{account}.blob.core.windows.net/{Path}/',item().name) to assign the value to the variable.
The output is as follows:

I am trying to check if any zip file exists in my SFTP folder. GetMetadata activity works fine if I explicitly provide the filename but I can't know the file name here as the file name is embeded with timestamp and sequence number which are dynamic.
I tried specifying *.zip but that never works and GetMetadata activity always returns false even though the zip file actually exists. is there any way to get this worked? Suggestion please.
Sample file name as below, in this the last part 0000000004_20210907080426 is dynamic and will change every time:
TEST_TEST_9999_OK_TT_ENTITY_0000000004_20210907080426
You could possibly do a Get Metadata on the folder and include the Child items under the Field List.
You'll have to iterate with a ForEach using the expression
#activity('Get Folder Files').output.childItems
and then check if item().name (within the ForEach) ends with '.zip'.
I know it's a pain when the wildcard stuff doesn't work for a given dataset, but this alternative ought to work for you.
If you are using exists in the Get Metadata activity, you need to provide the file name in it.
As a workaround, you can get the child items (with filename *.zip) using the Get Metadata activity.
Output:
Pass the output to If Condition activity, to check if the required file exists.
#contains(string(json(string(activity('Get Metadata1').output.childItems))),'.zip')
You can use other activities inside True and False activities based on If Condition.
If there is no file exists or no child items found in the Get Metadata activity.
If condition output:
For SFTP dataset, if you want to use a wildcard to filter files under the field specified folderPath, you would have to skip this setting and specify the file name in activity source settings (Get Metadata activity).
But Wildcard filter on folders/files is not supported for Get Metadata activity.
I hope you guys keep health and keep strong in Pandemic covid-19.
I have some question on Azure Data Factory. btw I have create some pipeline with Metadata activity with detail below:
I have file in Folder and Subfolder like this:
I have metadata activity with for each with first get metadata child item (in folder) like this:
metadata with last modified like this (if you setting like this, metadata only read last modified subfolder
after that add variable I use #item().Name to read file in that folder like this:
after running metadata which have subfolder, I've get error like this:
the error give info that with #item().Name cannot read subfolder on that folder. the metadata for each file is success, but error like this which on my activity cannot read metadata subfolder .
many big thanks to have answer, Thank You
If you need to access the folder
Create a clone of same dataset and setup parameter as below, leave the file field empty.
If you need to access the file inside directory, use condition #equals(item().type,'Folder') to identity directory then inside that use dataset with parameters for directory and file.
I want to copy the file from Source to target container but only when the Source file is new
(latest file is placed in source). I am not sure how to proceed this and not sure about the syntax to check the source file greater than target. Should i have to use two get metadata activity to check source and target last modified date and use if condition. i tried few ways but it didn't work.
Any help will be handy
syntax i used for the condition is giving me the error
#if(greaterOrEquals(ticks(activity('Get Metadata_File').output.lastModified),activity('Get Metadata_File2')),True,False)
error message
The function 'greaterOrEquals' expects all of its parameters to be either integer or decimal numbers. Found invalid parameter types: 'Object'
You can try one of the Pipeline Templates that ADF offers.
Use this template to copy new and changed files only by using
LastModifiedDate. This template first selects the new and changed
files only by their attributes "LastModifiedDate", and then copies
them from the data source store to the data destination store. You can
also go to "Copy Data Tool" to get the pipeline for the same scenario
with more connectors.

documentation
OR...
You can use Storage Event Triggers to trigger the pipeline with copy activity to copy when each new file is written to storage.
Follow detailed example here: Create a trigger that runs a pipeline in response to a storage event
I have an endpoint, you can have información about products
{{URL_API}}/products/
If i perform a GET method over that endpoint i will obtain the information of every product
BUT i can also specify the product that i want to know about, i.e:
{{URL_API}}/products/9345TERFER (the last code is the id of the product, called SKU)
The problem is that if i want to make a CSV in order to update the information of different products i have to define a variable called sku in the endpoint so i will be able to pass the corresponding SKU
I want to create the variable {{sku}} but i do not understand how to do that.. i tried so many times and i failed, i've searched a lot but i do not really understand
Also, should i use ":" before the declaration of the variable? i mean:
{{URL_API}}/products/:{{sku}}
or simply:
{{URL_API}}/ns/products/{{sku}}
Can you help me?
I'm super lost :(
EDIT:
I want to perform a PUT method, i want to pass different values to the body and then.. send the request (it throws an error: 404 not found)
This is what i did:
PUT|{{URL_API}}/products/{{sku}}
body:
{
"tax_percentage":"{{tax_percentage}}",
"store_code":"{{store_code}}",
"markup_top":"{{markup_top}}",
"status":"{{status}}",
"group_prices": [
{
"group":"{{class_a}}",
"price":"{{price_a}}",
"website":"{{website_a}}"
}
]
}
CSV:
POSTMAN:
Your issue seems to be just a basic understanding of how data files work with variables in Postman, here's a simple example that will work the same way for you too.
This is a basic request I'm using to resolve the variable from the data file - It's a GET request but that doesn't matter as all we're look at here is using a data file to resolve variables. All you need to do is ensure the URL is correct and that you SAVE the request before using the runner.
Here's a simple CSV file created in a text editor. The heading sku in the name on the variable it will reference inside the Postman request. Each value under that is the value that will be used for each iteration.
In the Runner, select your Collection from the list (If you have more than one) then select the CSV file. Once imported, you will be able to see a preview of the data.
If that's correct, press the Run button. The Runner will then iterate through the file and pick up the sku value in the CSV file and use it in the request. I've expanded one of the requests so you can see that the value was used in the request.
I have added custom column to store company logo. I have used file api of moodle like :
$mform->addElement('filepicker', 'certificatelogo', 'Company Logo', null,
array('maxbytes' => $maxbytes, 'accepted_types' => '*'));
$mform->setDefault('certificatelogo', '0');
$mform->addHelpButton('certificatelogo', 'certificatelogo', 'certificate');
Once the form is submitted itemid will be stored in custom column. Say "648557354"
Now I need to get image to print logo on certificate. How can I get image path from itemid? Do I need to store any other information to retrieve image?
The itemid returned is the temporary id of the draft area where the file is stored whilst the form is being displayed. You need to copy the file into its 'real' location, when the form is submitted, otherwise the file will be automatically deleted after a few days (and it will only be accessible to the user who originally uploaded it).
I'd always recommend using the filemanager element, if you are planning on keeping the file around (filepicker elements are for files you want to process and discard, such as when uploading a CSV file data to parse and add to the database).
Details of how to use it are here:
https://docs.moodle.org/dev/Using_the_File_API_in_Moodle_forms#filemanager
But the basic steps are:
Copy any existing files from the 'real' area to the draft area (file_prepare_standard_filemanager).
Display the form.
On submission, copy files from the draft area to the 'real' area (file_postupdate_standard_filemanager).
When you want to display the file to the user, get a list of files stored in the file area (defined by the component, filearea, context and, optionally, itemid, you used in file_prepare_standard_filemanager and file_postupdate_standard_filemanager). You can do this with: $fs = get_file_storage(); $fs->get_area_files().
For those files (maybe only 1 file, in your case), generate the URL with moodle_url::make_pluginfile_url.
Make sure your plugin has a PLUGINNAME_pluginfile() function in lib.php, to examine incoming file requests, do security checks on them, then serve the file.
There is a reasonable example of all of this at: https://github.com/AndyNormore/filemanager
