| | | | | | | | | | | | | | with declarative is sqlalchemy.ext.declarative.mapperproperty. Same thing, but moving there since it is more of a "marker" that's specific to declararative, not just an attribute technique. [ticket:1915]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - The exception raised by Session when it is used subsequent to a subtransaction rollback (which is what happens when a flush fails in autocommit=False mode) has now been reworded (this is the "inactive due to a rollback in a subtransaction" message). In particular, if the rollback was due to an exception during flush(), the message states this is the case, and reiterates the string form of the original exception that occurred during flush. If the session is closed due to explicit usage of subtransactions (not very common), the message just states this is the case. - The exception raised by Mapper when repeated requests to its initialization are made after initialization already failed no longer assumes the "hasattr" case, since there's other scenarios in which this message gets emitted, and the message also does not compound onto itself multiple times - you get the same message for each attempt at usage. The misnomer "compiles" is being traded out for "initialize".

| * - a large hill to climb. Added declarative examples to all theMike Bayer2010-08-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | "basic relationship" examples, cleaned up the examples and added some more explicitness. Also renamed "treenodes" to "nodes" and added self-referential declarative example. - Added info/examples on how to join tables directly when querying with joined table inheritance. - Starting to talk about hybrids in the main mapper docs some more. introducoed the idea that synonyms are on their way out. - SQL expressions as mapped attributes also gets better verbiage, alternative approaches to them, including hybrids. - modernized the hybrid example. - object_session() as a standalone function wasn't documented ?!

| * - Another pass through the series of error messagesMike Bayer2010-08-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | emitted when relationship() is configured with ambiguous arguments. The "foreign_keys" setting is no longer mentioned, as it is almost never needed and it is preferable users set up correct ForeignKey metadata, which is now the recommendation. If 'foreign_keys' is used and is incorrect, the message suggests the attribute is probably unnecessary. Docs for the attribute are beefed up. This because all confused relationship() users on the ML appear to be attempting to use foreign_keys due to the message, which only confuses them further since Table metadata is much clearer. - If the "secondary" table has no ForeignKey metadata and no foreign_keys is set, even though the user is passing screwed up information, it is assumed that primary/secondaryjoin expressions should consider only and all cols in "secondary" to be foreign. It's not possible with "secondary" for the foreign keys to be elsewhere in any case. A warning is now emitted instead of an error, and the mapping succeeds. [ticket:1877] - fixed incorrect "Alternate Collection Mappings" reference in the docs, not sure if someone wants to reference "Rows that Point to Themselves" function - "Collection Mapping" is "Advanced Collection Mapping", this section is troublesome since nobody really needs it but it is public API

| | | | | | | | | | | | | | mapper property attribute, it will be called to get the actual attribute value during initialization. Currently, there's no advantage to using @classproperty on a column or relationship attribute of a declarative class that isn't a mixin - evaluation is at the same time as if @classproperty weren't used. But here we at least allow it to function as expected. - docs for column_property() with declarative - mixin docs in declarative made more clear - mixins are optional - each subsection starts with, "in *declarative mixins*", to reduce confusion
