Another great video by warleyalex. This time, a full FishFacts demo in AJAX, using mORMot and its SQLite3 ORM as server. See it on YouTube! Feedback is welcome on our forum. Update: I've just uploaded the corresponding source code to our repository. See sample 19 - AJAX ExtJS FishFacts. You need to […]

TDataSet... now I'm confused
2013-04-22. Pascal Programming
You perhaps know that I'm not a big fan of the TDataSet /
RAD DB approach for end-user applications.
They are easy to define, almost no code to write, and you are able to publish a
working solution very fast.
But it is a nightmare to debug and maintain. I prefer the new
DataBinding feature, or... of course... ORM!
In mORMot, we have some auto-generated screens, and in our roadmap, we
forcast to use some auto-binding features, using a KISS by-convention MVC
pattern.
For some users, we made a ORM / TDataSet conversion unit.
And we discovered that TDataSet has a weird, and very
misleading definition of its AsString property, for Unicode
versions of Delphi.

Two videos about EXTjs client of mORMot server
2013-04-02. Open Source › mORMot Framework
Two nice videos, posted by a framework user. The first one presents a remote RESTful access of a SQLite3 database, hosted by a mORMot server: After one post in the forum, warleyalex was able to easily add remote filtering of the request: In addition to the previous video about security (by which the […]

Adding some generic-based methods to mORMot
2013-03-28. Open Source › mORMot Framework
We have just added a TSQLTable.ToObjectList<T: class>() method. I want to add some generics-based methods to mORMot, for newer versions of Delphi. What do you think of it? Have you some method prototypes to propose? My first concern is that FreePascal does not offer the same syntax. I suppose […]

Introducing TSQLTable.Step() method
2013-03-27. Open Source › mORMot Framework
We have just added TSQLTable.Step(), FieldBuffer() and
Field() methods, handling a cursor at TSQLTable
level, with optional late-binding column access.
It allows to retrieve results from a TSQLTable /
TSQLTableJSON result sets within a "cursor-like"
orientation.
That is, no need to specify the row number, but write a simple while
aList.Step do ... loop.
Of course, you should better use TSQLRecord.FillPrepare most of
the time, and access the data from a TSQLRecord instance.
But it can be very useful, e.g. when working on a custom JOINed SQL
statement.

Delphi is just a perfect fit for the average programmer
2013-03-26. Pascal Programming
On the Embarcadero
forums, some user did have a perfectly sane reaction, about a non obvious
integer type cast like Int64Var := Int32Var*Int32Var, which may
overflow.
We've got to stop becoming, as one poster put it, "human pre-compilers" for Delphi.
The compiler ought to have the common sense to not need the programmer to cast the two integer values.
I respectfully think just the opposite.
;)
Such a type cast is part of the language grammar.
If you know the grammar, you will know how it will be compiled.
To be honest, you have the same in all languages, with more or less range
checking, optimization, and implicit conversion.
This is why I like Delphi: it can be mastered by any programmers, whereas truly
mastering Java or .Net needs a genius.
Delphi is just... human...

Download latest version of sqlite3.dll for Windows 64 bit
2013-03-23. Open Source › mORMot Framework
Update: We now build the amalgamation file with mingw and release the latest version of SQLite3, from this direct SQLite3-64.7z link, as soon as it is published on the SQLite3 site. Up to now, there is no official Win64 version of the SQlite3 library released in http://sqlite.org.. It is in fact […]
