I'm currently using simple schema to manage my mongodb designs. I'm at a point where i have a number of collections and it can be a little difficult to visualize all of the collections while adding features to the app. Is there a graphical way to view the schema collections? Noob questions.
I'm not sure what you really want but if you're looking for a mongodb gui client then you can try MongoChef. But it's not interconnected to the simple schema package except if you're using collections2.
Hope this helps.
It is not possible to directly view the schemas of a collection until you have inserted a document.
I will advice seeding the collection with some sample data and then using meteortoys:allthings package to view the collections. (More info here)

We are in situation to create the separate API in Python FastApi for one functionality. Other functionality in Laravel. The application which exists already. It created set of tables and using them. Now, we are required to create Pydantic schemas for new API. That schema has a relationship with existing tables. We don't want to create separate schemas for existing tables.
We are forced to create schemas for existing tables as well in the new API. We don't want to create the separate schemas and models for existing tables.
Kindly suggest
Thanks in advance
If you don't care about automatic documentation you don't need to use pydantic at all - you can just return dict and use swagger. If you do, I have no good news.
As far as I know it's not easily achievable. Even if you have tables definitions implemented in sqlalchemy there is not easy way of creating schema from them (there is a tool but it's still experimental).
There are ORM's that can do that (like tortoise) but you still need to implement schema somewhere. Dynamic creation of python class based on database schema would be very hard, very long, very bugable and would break static checkers so I am pretty sure they never exist.
Working on my first Microsoft NoSQL application and I am struggling with architecture. The CosmosDB tutorials are understandably but frustratingly rather basic. The ToDo app tutorial here simply describes CRUD operations on a document of type Item - with very simple views and use of scaffolding.
My views are rather more complex and require additional information. I seem to have several options but I am unclear on the best approach. I could..
Make the JSON document fit my view. I am uneasy about this due to mixing of view and 'domain' data - but this is from my relational DB viewpoint. Also when I POST I will need to account for updating of duplicate view data within the same document.
Create a bunch of View Models and map these. This would be my normal apporach but this seems to add a signifcant overhead just to add a few extra fields to what is a JSON object. I have not looked at AutoMapper for .NET Core - perhaps this would be a more attractive option.
Use dynamics in some way. Microsoft has an example here.
Has anyone had a similar issue when moving to this new database - and could recommend an approach - and ideally point me to some online example/documentation?
Thanks!
Does Firebase offer a way to view and update our data in a more human-readable format, rather than large trees of text?
Parse has a great browser for viewing and updating tables of data, which I found invaluable. It was easy to find specific data, and columns had helper menus for creating pointers and references to objects in other objects/tables. It was also easy to translate spreadsheet data into databases of users/places/etc. I guess I'm looking for something similar in Firebase, if it exists.
Any help would be appreciated.
Firebase is a schemaless database. Since it stores the data as JSON, it offers a visualization of the data as an editable tree in your Firebase Console. It does not offer a table view, although you could easily create that yourself.
I have ben following through a tutorial that shows how to get started creating a Web Forms Application in ASP.NET...and have got to the part where you create Data Classes. These assume you are starting from scratch and generating the database from code - however - I already have a database created and populated from elsewhere.
Entering line by line to create the Class for each table seems very laborious. (I'm using VB.Net and VS 2013 by the way)
Q1. Can anyone help by suggesting a more automated way of doing this? Surely there is a tool to grab the schema?
Q2. Although the tutorial mentions Entity Framework and Code Behind briefly - having done some reading and research - I am very confused by all of the different terms for data access. Am I using ADO.NET ?? Is the methodology called Code Behind as opposed to something else? Are there better ways to connect to a database and Read/Update/Delete records.
Q3. If I want to use a Data Grid to show the data do I use the generated classes to do this - or just 'bind' the grid directly to the database?
I have been a developer for 40 years but the newer .Net models are causing me some confusion so any advice gratefully received. (and any simple books or tutorials that can be suggested would be helpful).
Thanks
Q1: What you want is to generate "EF Designer from database" by using a Entity Data Model.
In your project add a new item and look under "Data".
What this technique does is auto generating entity classes from your predefined database.
Q2: I suggest you read Getting started with Entity Framework. "Database First" is just a description of how you want to use the Entity framework - by saying you already have a database structure.
Q3: In this case if you use Entity Framework and the "database first" mechanism to generate entities you can databind the gridview from the result of a entity LINQ query, please see this example: Tutorial: Databinding
I'm attempting to setup Entity Framework using Code First on an existing database. The database isnt in great shape (poor naming convention and some constraints are needed). The application I'm building is an MVC app. I have a "Model", "Repository", and "Web" (mvc) tiers.
To setup EF and map my model objects (POCO objects), is it required that I match my objects to database tables? Can I, instead, use my own stored procedures for CRUD operations? Would it help if I use WCF data services?
I'm planning on using fluent configurations to map my objects, but having some issues due to the database schema. I'm know considering redesigning the database just to get EF to map correctly. Any suggestions would be greatly appreciated!!
Looks awfully similar to this question:
Does Entity Framework Code First support stored procedures?
The answers there may be helpful to you, as well as the discussion surrounding how Code First and Stored Procedures don't make a whole lot of sense.
Wow, Julie Lerman answered!
Yes, it's possible, but not particularly easy. In particular, you must call context.Database.SqlQuery<T>() where T is the entity type you want to return, and your SQL must match up to that entity type. Otherwise, you will have to massage a result set into a type.
In general, you will have to do most of this manually, although you could probably figure out a T4 template to generate it for you, or maybe use some other tool like CodeSmith.
