I have many end users for my reports. Some of them want to look at all website data, some just section A, some section B, etc. For my own sanity and not having to create the same report over and over with different filters, I'm wondering if there's either:
A way to provide a link to a report where the link tells data studio what filter to apply to the report
A way to filter the report based on the user who's logging in.
I have the impression that neither of these is possible, and it seems like people are reluctant to have one dashboard that they have to proactively filter for their section (I'm still going to try that). But I'm hoping that there's perhaps something I didn't know about.
This is possible using Custom bookmark links (doc). The Drill down table example (doc) shows how you can create a table with records linking to a second page of the dashboard with different filters. You could use this to create filter pre-sets for different users groups.
This is currently not possible.
I'm working on a portal based on Orchard CMS. We're using Orchard to manage the "normal" content of the site, as well as to model what's essentially data for a small application embedded in it.
We figured that doing it that way is "recommended" for working in Orchard, and that it would save us duplicating a bunch of effort in features that Orchard already provides, mainly generating a good enough admin UI. This is also why we're using fields wherever possible.
However, for said application, the client wants to be able to display the data in the regular UI in a garden-variety datagrid that can be filtered, sorted, and paged.
I first tried to implement this by cobbling together a page with a bunch of form elements for the filtering, above a projection with filters bound to query string parameters. However, I ran into the following issues with this approach:
Filters for numeric fields crash when the value is missing - as would be pretty common to indicate that the given field shouldn't be considered when filtering. (This I could achieve by changing the implementation in the Orchard source, which would however make upgrading trickier later. I'd prefer to keep anything I haven't written untouched.)
It seems the sort order can only be defined in the administration UI, it doesn't seem to support tokens to allow for the field to sort by to be changed when querying.
So I decided to dump that approach and switched to trying to do this with just MVC controllers that access data using IContentQuery. However, there I found out that:
I have no clue how, if at all, it's possible to sort the query based on field values.
Or, for that matter, how / if I can filter.
I did take a look at the code of Orchard.Projections, however, how it handles sorting is pretty inscrutable to me, and there doesn't seem to be a straightforward way to change the sort order for just one query either.
So, is there any way to achieve what I need here with the rest of the setup (which isn't little) unchanged, or am I in a trap here, and I'll have to move every single property I wish to use for sorting / filtering into a content part and code the admin UI myself? (Or do something ludicrous, like create one query for every sortable property and direction.)
EDIT: Another thought I had was having my custom content part duplicate the fields that are displayed in the datagrids into Hibernate-backed properties accessible to query code, and whenever the content item is updated, copy values from these fields into the properties before saving. However, again, I'm not sure if this is feasible, and how I would be able to modify a content item just before it's saved on update.
Right so I have actually done a similar thing here to you. I ended up going down both approaches, creating some custom filters for projections so I could manage filters on the frontend. It turned out pretty cool but in the end projections lacked the raw querying power I needed (I needed to filter and sort based on joins to aggregated tables which I think I decided I didn't know how I could do that in projections, or if its nature of query building would allow it). I then decided to move all my data into a record so I could query and filter it. This felt like the right way to go about it, since if I was building a UI to filter records it made sense those records should be defined in code. However, I was sorting on users where each site had different registration data associated to users and (I think the following is a terrible affliction many Orchard devs suffer from) I wanted to build a reusable, modular system so I wouldn't have to change anything, ever!
Didn't really work out quite like I hoped, but to eventually answer the question in your title: yes, you can query fields. Orchard projections builds an index that it uses for querying fields. You can access these in HQL, get the ids of the content items, then call getmany to get them all. I did this several years ago, and I cant remember much but I do remember having a distinctly unenjoyable time with it haha. So after you have an nhibernate session you can write your hql
select distinct civr.Id
from Orchard.ContentManagement.Records.ContentItemVersionRecord civr
join civ.ContentItemRecord cir
join ci.FieldIndexPartRecord fipr
join fipr.StringFieldIndexRecord sfir
This just shows you how to join to the field indexes. There are a few, for each different data type. This is the string one I'm joining here. They are all basically the same, with a PropertyName and value field. Hql allows you to add conditions to your join so we can use that to join with the relevant field index records. If you have a part called Group attached directly to your content type then it would be like this:
join fipr.StringFieldIndexRecord sfir
with sfir.PropertyName = 'MyContentType.Group.'
where sfir.Value = 'HR'
If your field is attached to a part, replace MyContentType with the name of your part. Hql is pretty awesome, can learn more here: https://docs.jboss.org/hibernate/orm/3.3/reference/en/html/queryhql.html But I dunno, it gave me a headache haha. At least HQL has documentation though, unlike Orchard's query layer. Also can always fall back to pure SQL when HQL wont do what you want, there is an option to write SQL queries from the NHibernate session.
Your other option is to index your content types with lucene (easy if you are using fields) then filter and search by that. I quite liked using that, although sometimes indexes are corrupted, or need to be rebuilt etc. So I've found it dangerous to rely on it for something that populates pages regularly.
And pretty much whatever you do, one query to filter and sort, then another query to getmany on the contentmanager to get the content items is what you should accept is the way to go. Good luck!
You can use indexing and the Orchard Search API for this. Sebastien demoed something similar to what you're trying to achieve at Orchard Harvest recently: https://www.youtube.com/watch?v=7v5qSR4g7E0
In CRM Online on a customer form is there anyway that you can check if the Associated View for Assets is blank? And if its blank change a field value based on it.
Using JavaScript, 2 ways:
The associated grid is showing records related to your primary record. You can perform the same query the grid is doing using REST which will tell you if there are any records. You can then count the records, and change the field value as required. This approach is better if there are records in the database but which aren't shown in the view for some reason, e.g. view filters.
Access the Grid objects data using getRows(). As above you can then count the records, and change the field value as required. The downside of this is I believe those methods only give you access to the records shown on the form (and not any hidden by filters but still in the database) - but I don't think that that will be a problem here.
Worth bearing in mind that this approach only works client side, e.g. someone has to be actually looking at the form.
If you need to cover the a non-client side approach, e.g. workflows creating records, then you should probably look at plugin development so the changes can be performed server side.
As a side if you just want a simple count shown on form you then you should probably look at Calculated Fields and in particular Rollup fields. You might also be able to run further client side JavaScript from the count.
I want to have multiple filters in an APEX report but it seems it's not possible? I'm new to apex so it's quite possible too I just don't know how to do it.
I've searched around the net and looked at the various settings in the APEX page but I can't find what I'm looking for.
Like in this screenshot: http://i.imgur.com/3j3wOIG.png
I can only have 1 filter available. I want to filter on other fields too including fields which are not in the report columns.
Is this possible? If yes, can you please teach me? thanks
Columns that aren't displayed in your report are not rendered on your page, therefore you can not filter on them. If you want do so anyway, you need to create a filter based on page items, which you can append to your report query in the where clause.
e.g. create a page item P1_FILTER1 and reference it in your query as: "...where my_column = nvl(:P1_FILTER1,my_column)".
To ensure data consistency you can best create your page item as a select list.
I use paging in Codeigniter, and I would like to display by default 15 records per page. However, I would like to give the user option to choose how many records per page he would like to see, selecting from the dropdown 30, 50, 100 or all records.
Since I will have this code on more than one place, I would like to avoid repeating same code trough my controllers. Anyone know which is right way how to implement this option according to MVC philosophy? Should this code be placed in some config file?
Either a library, or a helper, would be the best place to have code that is re-used in multiple places
If you want to store the users preference, so your application remembers it, then either store it in the session, or the database.
