Unfortunately this is not an option because of the atom limit. This would be easy, if we just cast all the strings to atoms. """īut for multiple reasons we would like to use the query language. We could simply write a raw query to get the data. To select the records from the database we basically have everything available as strings: schema = "my_schema" So tables and columns are defined by the user at runtime. Our current pattern has been to use the Ecto.Query Macro API to define queries. Currently, we are using a Postgres database, and have defined a number of schemas in Ecto, some of which have associations. This will be applied to all fromĪnd joins in the query that did not have a prefix previously givenĮither via the :prefix option on join/ from or via the schema.I am wrapping my head around this for days now… how can you select dynamic columns defined by the user at runtime? There are numerous threads about similar problems. Hello everyone, My team and I are looking for perspectives on best-practices when defining associations in Ecto.

Keep in mind this update_all will not update autogenerated Not all databases support returning data from UPDATEs. Unless a select is supplied in the update query. It returns a tuple containing the number of entries and any returned Updates all entries matching the given query with the given values. Init/2 repository callback: def init ( _type, config ) do Reading a system environment variable, such can be done via the

Shows how to pass these configuration values: config :my_app, Repo, url : case the URL needs to be dynamically configured, for example by Options, like ssl, timeout and pool_size.

If false,ĭisables logging for that repository. Elixir, Ecto, Tables without 'id' in Relationships. Can be any of Logger.level/0 values or false. Let’s start with some basic queries to get a feel for Ecto’s querying DSL. :log - the log level used when logging the query with Elixir's :url - an URL that specifies storage information. It must always point to a subdirectory inside the priv directory This matches my modelling (via Object Role Modelling) where I use singular entities/types. :priv - the directory where to keep repository data, like Personally I prefer singular based on what each row' stores: Order, Product, User, Item, etc. :name- The name of the Repo supervisor process

This means that dynamic table names are not possible. Note that the name must be a compile-time string literal, as noted in the docs. We will also need to provide the CTE with a name. Creating the query requires the use of fragments, as well as specifying the data type for each interpolated column.
