I'm using Google Data Studio to visualize results from various queries (from different tables within the same BigQuery-database).
For this reason, I created and use multiple data-sources-connectors. Each one of them has a SQL query included and makes use of an defined input parameter (which can be changed by report editors) - called "userid". It is the same id for all queries and resulting charts.
However, when I click "Manage URL parameters", I'm not allowed to use the same URL parameter for more than one data source (instead they are called ds0, ds1, ds2 etc - although they all end up being used as "userid").
If I add a data source under File - Report Settings, a new field "userid" appears, which I can alter - this will update ALL charts in the report with the very same userid (as expected). This works, but I do want to make use of an url which delivers an report with all updated queries depending on ONE userid.
Therefore, I guess I'm overseeing something - it should be possible to just use one query parameter to update the same "userid" for all queries in all data connectors? Or have I overlooked the possibility to fire multiple queries within one data source connector? Or is it expected to create a looong url full of redundant query parameters in this case?
I'm curious for your input!
Best regards :)
There does not seem to be any good solution for this.
For now the best workaround seems to be to just repeat the parameter multiple times -- it's ugly but it works. For example, use the URL parameter mapping screen to call the parameter u1, u2, etc., and then just pass all of them:
?params={"u1":"foo","u2":"foo"}
(URL encoded of course)
The ugliness is mostly for us developers: it violates our sense of DRY and clean code, and makes the URL much longer than it needs to be. However, most people don't care or know about the URL parameters so its irrelevant to them.
The bigger downside is that when the URL is distributed to clients (bookmarks, mobile apps), every time new data sources are added that require the same URL parameters, a new URL has to be distributed to clients for no good reason. A workaround for this is to build the URL dynamically via a simple redirector function.
This issue https://issuetracker.google.com/issues/180705297 is a feature request to implement this capability.
If you group the elements that you want to control with the same parameter (select and then shift G) then it will give you options to select the data source and the params box to apply to the group.

When we design Rest apis, it is said that use Path Variable when you need to identify a resource and Request Parameters when you need to do operations like sorting, filtering, searching, pagination. Let us take a scenario of Employee:
Employee has three fields like name, companyName, socialSecurityNo.
Now i want an Employee with a socialSecurityNo = ABC.
It seems fine to have endpoint with path variable like /employees/{socialSecurtityNo}, since we are identifying a resource.
Also it seems intuitive that we are filtering on the basis of socialSecurityNo and have an endpoint like /employees?socialSecurityNo=ABC
What will be the right way as i am confused and think that both apply.
It's a good question.
/employees?socialSecurityNo=ABC
is filtering all employees on socialSecurityNo. If socialSecurityNo is unique to an employee, there's no point in this endpoint existing and a client should use /employees/{socialSecurtityNo}.
There's nothing wrong with filtering on a unique field value (socialSecurtityNo) and if a client finds it easier to use this version (for whatever technical reason) then that's fine. There is no 'right' way. The ultimate reason APIs exist is to allow valuable work to be done by a client. Work with the client to allow that to happen but keep best practice in mind and know when the solution isn't the best but is the most practical in the situation.
I would expect to see:
/employees?surname=Smith
as this is filtering on a non unique field value and should return a collection of Employee objects.
The 'right' thing to do is keep the results consistent. If you have both ways of finding an employee, make sure the returned result is the same in each case.
On the saving of Case record I want to assign the case to respective Agent based on case type , sub type and Client/Account,
I have a Assignee field on Account form which I need to get the Agent's name to Assign the case.
I am creating a custom workflow activity for that, but while writing it I stuck how to fetch Case forms record on which I apply logic.
Please suggest what is the good approach, do I need to make a retrieve call to fetch these parameters or something else.
While setting the Custom Step Input Properties drop down fields are not populating to select the Dynamics Values.
Better to use plugin, as the documented/supported preimage is available in plugin steps + flexible.
You have to look for type, subtype, etc in target entity (incident in your case) or preimage if needed to apply logic.
If you still want to use workflow, go ahead & follow this article.
we can always read Pre image and Post image in the plug-in for various purpose. However, in workflow, we may sometimes want to read Pre Image for some purpose. Now we can also read Pre Images and Post Images in the workflow using Execution Context. It uses the same Plug-in Architecture and hence we can use it to read Pre Images and Post Images. However, this concept is not documented in the SDK so it might be unsupported.
Is it possible with a FHIR search procedure to search for TWO resource types and sort them according to the date? I'd like a list of Observation and QuestionnareResponses, in a single response, returning the newest 10 regardless of resource type.
Searching for one would be:
http://apps.ehelselab.com/baseDstu2/Observation?_sort:desc=date
Any query using the standard "search" capability is always against exactly one resource type. You can include referencing and referenced resources, but filtering and sorting are always done against the "base" resource for the search. To do what you're interested in doing, you have a few options:
define a custom query using the OperationDefinition mechanism (only works if you've got a direct relationship between client and server systems so you can ensure all participants support the operation
Use a "Batch" to execute queries against both, then interpolate the results as you page through both result sets
You can do a query just on the "base", however there isn't presently a way to constrain the types of resources returned - you'd need a custom search criteria
You might be able to use the _filter mechanism - I haven't dived into it very deeply. But I suspect that it also uses the "single target resource type" approach.
The best bet is probably #3. If you submit a request to add a search criteria to "Resource" allowing constraining the resource type, that would probably let you do what you wanted.
Is there another way to view the profiling results of MiniProfiler (I'm specifically interested in EF5 version)?
Every tutorial that I've seen uses MiniProfiler.RenderIncludes(); but since my MVC app mostly returns JSON, that is not an option for me.
Is there a way to write results to file or something like that?
You can read and write results to just about anywhere by changing the MiniProfiler.Settings.Storage to a different IStorage implementation from the default (which stores to http cache). If you wanted to, this could store to and read from a file pretty easily (you would have to write your own custom implementation for that).
The files served by RenderIncludes are the html templates for displaying the results and the script to retrieve the results from the server and render them on the client (all found here). But you are by no means obliged to use this mechanism. If you want to write your own logic for retrieving and displaying results, you should base this off of the logic found in MiniProfilerHandler.GetSingleProfilerResult. This function roughly performs the following (putting in the siginificant steps for your purposes):
Gets Id of next results to retrieve (through MiniProfiler.Settings.Storage.List())
Retrieves the actual results (MiniProfiler.Settings.Storage.Load(id))
Marks the results as viewed so that they wont be retrieved again (MiniProfiler.Settings.Storage.SetViewed(user, id))
Converts these to ResultsJson and returns it
With access to MiniProfiler.Settings.Storage, you should be able to retrieve, serve and consume the profile results in any way that you want. And if you are interested in using the RenderIncludes engine but want to mess around with the html/js being served, you can provide your own custom ui templates that will replace the default behavior.
I've been having a look at several MVC frameworks (like rails, merb, cakephp, codeignitier, and similars...)
All the samples I've seen are basically plain and simple CRUD pages, carrying all the infr needed in the querystring and the posted field values.
I've got a couple of apps made with some sort of framework built with classic asp.
This framework handles some CRUD stuff a little more complex than the examples I found.
Something like master-detail, filtering by example, paging, sorting and similars.
I have a controller class that it's just a finite state machine, that goes thru diferent states (like new, browse, filter, show, etc.), then performs the appropiate action depending on the event raised and finally retrieves the neede info to the calling page.
To achieve this I have several hidden inputs to keep the state of the web page (like current id, filter criterias, order criterias, previous state, previous event, well, you get the idea)
What do you think would be the finnest approach to achieve this kind of funcionality?
hidden inputs built in the view and used from the controller??? (I guess that would be the equivalent of what I'm doing right now in classi asp)

(added in response to tvanfosson)
basically, my question refers to the third category, the context-dependent setting (in respect to the other two categories I agree with you) the info I was storing in hidden fields to store them on the querystring, I guess that when you click on the "next page" you include everything you need to save in the querystring, right? so that piece of query string gets appended in each and every link that performns some kind of action...
I'm not sure, what are the advantages and disadvantages of using the querystring instead of hidden inputs???
I use different strategies depending on the character of the actual data. Things that are preferences, like default page size, I keep in a Preferences object (table) that is associated with the current logged in user and retrieve from there when needed.
Persistent settings associated with the current logon, like filter settings for a page, are stored in the user's session. Generally these are things that if a user sets them in the current session they should remain sticky. I think filter settings and visibility are like this. If I filter a list, navigate away from it to drill down into a particular item, then come back to the list, I want my filter settings to be reapplied -- so I make it part of the session.
Context-dependent settings -- like the current sort column or page number, are controlled using query parameters. Paging and sort controls (links) are built with the appropriate query parameters to "do the right thing" when clicked and pass any necessary query parameters to maintain or update the current context of the control. Using the query parameters allows you to use an HTTP GET, which is bookmarkable, rather than a POST. Using hidden form parameters makes it much harder for the user to save or enter a URL that takes them directly where they want to go. This is probably more useful for sorting than it is for paging, but the principle applies equally.
