I'm using Google Firestore for a project and the "Cloud Firestore" interface for dealing with the database expands all document fields by default. This makes it tough to alter the data as I have a few large arrays in my sample data that cause me to have to collapse many fields before reaching the desired field.
Is there a way to set the data/fields to be collapsed by default? This is mainly a quality of life thing while I'm in MVP mode. For reference I've checked the documentation, reddit and stack overflow for an answer but haven't found a solution. I've also submitted this as a feature request just in case.
Edit for comment:
To clarify, I am referring to the console.firebase.google UI for Firestore. See the attached image (random image from google) for reference.
It's not possible to change the behavior of the console in the way you're suggesting. The way in which you add the data makes no difference.

We recently introduced GraphQL to our project, I've never used it before, however I like it a lot.
We decided to go with the HotChocolate library for .NET Core and Apollo for client side.
One thing I am not quite sure is about mutations, specifically peforming updates and partial updates with mutations.
I read somewhere that the practice is and that I should stick with creating specific mutation for each update, for instance updateUsername(), updateAddress(), updateCity() all of them should have specific mutation.
Issue with that is that my codebase will grow enormously if I decide to go in that direction, as we are very much data driven, with a lot of tables and columns per table.
Another question is, how to handle nullable properties, I can create a mutation which accepts some input object, but I'll end up with my entity being overwritten and all nullable properties not provided on the calling end will be set to null.
Is there a way to handle this update partially or I should go with specific update mutation for each property I want updated?
I think you understood the best practice around specific mutations wrong. It's less "have one mutation to update one field" and more "have specific mutations that encapsulate actions in your domain". A concrete example would be creating an "addItemToBasket" mutation, instead of having 3 mutations that update the individual tables related to your shopping basket, etc.
GraphQL is very much centered around front-end development, so your mutations should, in general, closely resemble actions a user can perform in your front-end. E.g. your front-end has an "Add to basket" button and your backend has an "addItemToBasket" mutation that resembles the action of placing an item in the user's basket.
If you design your mutations with this in mind, most of the time you shouldn't be having an issue with partial updates, since the mutation knows exactly what's to do and you are not just letting the user of your schema update fields at will.
If for whatever reason you need to have these partial updates, you likely won't get around implementing the patching yourself, unless your data provider supports it. Meaning you will have to have an input object type with nullable properties and your mutation that decides which fields have been changed and changing them using your data provider.
That being said, there's also a proposal for patching types in the Hot Chocolate repository that should simplify the patching part: https://github.com/ChilliCream/hotchocolate/issues/1326
for instance updateUsername(), updateAddress(), updateCity() all of them should have specific mutation.
Issue with that is that my codebase will grow enormously if I decide
to go in that direction, as we are very much data driven, with a lot
of tables and columns per table.
Correct. That's practically impossible to follow that way for more or less big data-driven applications.
Consider how we implement the patching in our API here. Also consider following the discussion about the patching feature in HotChocolate github thread. Hope, that helps!
I have been exploring Azure Form Recognizer for one of my project where we wants to perform OCR on some hand written texts.
The problem is that when we give scanned images to the tool to process, it some time doesn't even recognize the text written on it (even if it is clearly written). I tried multiple type of images by performing enhancement on it and also the B/W or colored copy of it but it doesn't works.
Some times it recognize value of two fields as one and this leads to incorrect data where one field is completely blank and other is having value of other one along with its own.
When there is NO VALUE in the tagged field in the testing data, it try to read the from some other place which is not even closer to that field or sometimes un-tagged
Could you please help with these queries.
Thanks in advance.
Can you please share also sample forms please make sure data is anonymized and without any real data ?
Please contact customer service to debug this issue.

Could someone please give some basic code on how to update items? I am using it an have an app that needs to add/delete values to list and map properties on table items without completely deleting the value. I also have a number property that I need to use as counter. In AWS documentation it simply states to re-save the entire object. I know it is possible to update items in this manner however I cannot seem to find any code. My app is in objective c however this seems like a problem for many people using many languages so this may be a great place to answer this for any and all languages. Thanks.
I am new to android and java and working on an app that has a few remaining problems that I haven't resolved yet.
I have a main activity that is a viewPager, with each page being a fragment. If the 4 fragments 3 are extended from ListFragments and one from PreferencesFragment.
The ListFragments have CursorAdapters to get data to and from SQLite databases through providers.
I am able to get data into the database, insert, modify and query the data correctly and fill the list views ok.
My preference setting are to choose different ways of viewing the data in the database.
Not knowing how to do this, I have implemented a process where I modify the cursorLoader query to the provider with a number of different choices of the "WHERE" clause. I have worked out the logic for the preferences as they exist now, implemented the code but had some difficulty finding what to try to trigger the refresh of the ListView.
Since the "dataset" hasn't really changed, no trigger can come from there, plus that would just use the same cursor as it currently exists to run the query again and return the same results (or be smart enough to know that it doesn't need to run).
On Stack Overflow I did find a couple of references to a similar implementation that suggested reStarting the cursor loader, which would then on the reStart read the current values in the stored Preferences file, create a now modified WHERE clause that will show the sub-set of data as specified in the preference settings.
In testing the app now, even with the reStart of the cursorLoader, the ListView isn't getting refreshed.
The only time I can get it to work right is restarting the app. If I stop the app and restart it, the new values are used and the ListView presents as the preferences dictate.
In looking through Stack Overflow and the Android site, I did find another set of APIs that might have been a more natural fit for what I am trying to do, namely the Filter APIs.
First question then would be, did I go in the wrong direction on how to control the "filtered" view of the datbase. Is filtering a better approach and a recommended way of
doing what I am trying to do?
Second question would be related to the fragment lifecycle of my ListFragments to achieve this CursorLoader update.
Thanks for any input on the topic.

Found my problem here.
Two things, the way I am trying filtering is working and from what I have seen in the
Android development site, a reference there indicated that the filtering capability is
already implemented in the CursorAdapter, CursorLoader classes I am using.
When my preference settings changed, I did a reStart of the cursorLoader, but had restarted the wrong one.
Problem solved. Any input on is there a better way would be appreciated.

we want to realize the following:
Generate PDF with Template,which means set value in AcroFields
Create a big details table (structure of table is also in template). In this progress, the details will occupy more than one page.
If the detail table is on multi pages, the header of the table should be also on top of the new page.
We found some examples on following website:
http://kuujinbo.info/cs/itext_template1.aspx
http://kuujinbo.info/cs/itext_template2.aspx
But the details the founction is omitted there.
Add content; the code for _do_form_fields(), _get_transaction_details(), and _transaction_summary() are omitted, since they only return strings to add to ColumnText. ColumnText is smart; each call to Go() renders as much text that will fit on the current page and returns a status code that tells you: (1) how much text (to write) is remaining, and/or (2) how much space is still available on the page. On each iteration you add text to the current page, call ColumnText.HasMoreText() to inspect the status, and then Document.NewPage() if necessary.
Is there anyone who had same situation before? We are appreciated that you could offer some tips or suggestions.
Thank you.
best regards,
Cheng Gong
You are already making a mistake in the first step of your requirements.
You say "Generate PDF with Template,which means set value in AcroFields."
The first part is OK: you want to generate a PDF with a template. However, this doesn't mean setting values in AcroFields. That's only one option. It's the option you take if you consider PDF being the digital equivalent of paper. The form is static: every coordinate is fixed. You just fill out data at the appropriate places. If the data doesn't fit the designated areas, you're out of luck. I already referred to chapter 6 of my book in a comment. You can also see how AcroForms work in a longer tutorial: https://www.youtube.com/watch?v=6YwDME0Fl1c (This tutorial is almost completely dedicated to creating a report from a data set.)
Another way to create PDF from a template is by using the XML Forms Architecture. In this case (if you have a pure XFA form), your PDF is a container for XML. You can then inject XML data into this form and the form will adapt itself depending on the data. A one-page form can easily grow into a 20-page document when filled out. This is explained in this video: https://www.youtube.com/watch?v=h0wzj84tnmw (Note that the video dates from 2012. The product I present has been finished and the results are much better now.)
Alternatives to this approach could be to create a template in HTML. I often refer to this solution as a poor man's XFA solution. This solution requires XML Worker. You can see an example in this video: https://www.youtube.com/watch?v=clWoDrEEl50
This is a general answer. I couldn't be more specific because your question isn't clear. You first need to make your mind up regarding the approach. Right now, you talk about AcroFields and at the same time about ColumnText. In the long tutorial, this is described as the hard way. See also the corresponding online samples. It is very confusing why you're asking a very difficult question before asking the simple questions. Unless of course, you already have the answer to those simple questions. If so, please share these answers.
