Command-line interface: flectra-bin¶
Running the server¶
database(s) used when installing or updating modules. Providing a comma-separated list restrict access to databases provided in list.
For advanced database options, take a look below.

host for the database server
UNIX socket otherwise
port the database listens on, defaults to 5432
hides databases that do not match
<filter>. The filter is a regular expression, with the additions that:
%his replaced by the whole hostname the request is made on.
%dis replaced by the subdomain the request is made on, with the exception of
www.flectrahq.comboth match the database
These operations are case sensitive. Add option
(?i)to match all databases (so domain
(?i)%dmatches the database
Since version 11, it’s also possible to restrict access to a given database listen by using the –database parameter and specifying a comma-separated list of databases
When combining the two parameters, db-filter supersedes the comma-separated database list for restricting database list, while the comma-separated list is used for performing requested operations like upgrade of modules.
$ flectra-bin --db-filter ^11.*$
Restrict access to databases whose name starts with 11
$ flectra-bin --database 11firstdatabase,11seconddatabase
Restrict access to only two databases, 11firstdatabase and 11seconddatabase
$ flectra-bin --database 11firstdatabase,11seconddatabase -u base
Restrict access to only two databases, 11firstdatabase and 11seconddatabase, and update base module on one database: 11firstdatabase. If database 11seconddatabase doesn’t exist, the database is created and base modules is installed
$ flectra-bin --db-filter ^11.*$ --database 11firstdatabase,11seconddatabase -u base
Restrict access to databases whose name starts with 11, and update base module on one database: 11firstdatabase. If database 11seconddatabase doesn’t exist, the database is created and base modules is installed
when creating new databases from the database-management screens, use the specified template database. Defaults to
Path to the PostgreSQL binaries that are used by the database manager to dump and restore databases. You have to specify this option only if these binaries are located in a non-standard directory.
Suppresses the ability to list databases available on the system
Control the SSL security of the connection between Flectra and PostgreSQL. Value should bve one of ‘disable’, ‘allow’, ‘prefer’, ‘require’, ‘verify-ca’ or ‘verify-full’ Default value is ‘prefer’

qweb: break in the evaluation of qweb template when a node contains

Flectra also provides debugging pseudo-levels which apply to different sets of loggers:

--log-level debug --log-request

--log-level debug --log-request --log-response
countis not 0 (the default), enables multiprocessing and sets up the specified number of HTTP workers (sub-processes processing HTTP and RPC requests).
multiprocessing mode is only available on Unix-based systems
A number of options allow limiting and recycling workers:
Number of requests a worker will process before being recycled and restarted.
Defaults to 8196.
Maximum allowed virtual memory per worker. If the limit is exceeded, the worker is killed and recycled at the end of the current request.
Defaults to 2048MiB.
Hard limit on virtual memory, any worker exceeding the limit will be immediately killed without waiting for the end of the current request processing.
Defaults to 2560MiB.
Prevents the worker from using more than <limit> CPU seconds for each request. If the limit is exceeded, the worker is killed.
Defaults to 60.
Most of the command-line options can also be specified via a configuration
file. Most of the time, they use similar names with the prefix

--save will save the current configuration state back
to that file. The configuration items relative to the command-line are to be
specified in the section
Here is a sample file:

Flectra command-line also allows to launch flectra as a python console environment. This enables direct interaction with the orm and its functionalities.
$ flectra_bin shell
Specify a preferred REPL to use in shell mode.
Scaffolding is the automated creation of a skeleton structure to simplify bootstrapping (of new modules, in the case of Flectra). While not necessary it avoids the tedium of setting up basic structures and looking up what all starting requirements are.
Scaffolding is available via the flectra-bin scaffold subcommand.
$ flectra_bin scaffold my_module /addons/
the name of the module to create, may munged in various manners to generate programmatic names (e.g. module directory name, model names, …)
directory in which to create the new module, defaults to the current directory
a template directory, files are passed through jinja2 then copied to the
This will create module my_module in directory /addons/.
Flectra CLI supports database population features. If the feature is implemented on a given model, it allows automatic data generation of the model’s records to test your modules in databases containing non-trivial amounts of records.
$ flectra_bin populate
list of models for which the database should be filled
population size, the actual records number depends on the model’s
_populate_sizesattribute. The generated records content is specified by the
_populate_factories()method of a given model (cf. the
populatefolder of modules for further details).
--addons-pathoption is required to specify the path(s) to the module folder(s).
--path, the count will be that of the sum of both options’ results (with possible overlaps). At least one of these two options is required to specify which code to process.
$ flectra-bin cloc --addons-path=addons -d my_database
--database, the count will be that of the sum of both options’ results (with possible overlaps). At least one of these two options is required to specify which code to process.
$ flectra-bin cloc -p addons/account
Multiple paths can be provided by repeating the option.
$ flectra-bin cloc -p addons/account -p addons/sale
--databaseoption is used.
Specify a configuration file to use in place of the
$ flectra-bin cloc -c config.conf -d my_database
Show the details of lines counted for each file.
Flectra Cloc counts the lines in each file of extra installed modules in a given database. In addition, it counts the Python lines of server actions and custom computed fields that have been directly created in the database or imported.
Some files are excluded from the count by default:
The manifest (
The contents of the folder
The tests defined in the folder
The migrations scripts defined in the folder
The XML files declared in the
demo_xmlsections of the manifest
For special cases, a list of files that should be ignored by Flectra Cloc can be defined
per module. This is specified by the
cloc_exclude entry of the manifest:
"cloc_exclude": [ "lib/common.py", # exclude a single file "data/*.xml", # exclude all XML files in a specific folder "example/**/*", # exclude all files in a folder hierarchy recursively ]
**/*can be used to ignore an entire module. This can be useful to exclude a module from maintenance service costs.
This method works the same as with the –database option if a manifest file is present in the given folder. Otherwise, it counts all files.
Identifying Extra Modules¶
To distinguish between standard and extra modules, Flectra Cloc uses the following heuristic:
modules that are located (real file system path, after following symbolic links)
in the same parent directory as the
standard modules are considered standard. Other modules are treated as extra modules.
Some file cannot be counted by Flectra Cloc. Those file are reported at the end of the output.
Max file size exceeded¶
Flectra Cloc rejects any file larger than 25MB. Usually, source files are smaller than 1 MB. If a file is rejected, it may be:
A generated XML file that contains lots of data. It should be excluded in the manifest.
Flectra Cloc cannot count the lines of code of a Python file with a syntax problem.
If an extra module contains such files, they should be fixed to allow the module to
load. If the module works despite the presence of those files, they are probably
not loaded and should therefore be removed from the module, or at least excluded
in the manifest via
