Tables management module

[ablayelana]

I installed the latest version of Mapmint successfully. However I do not have the tables management module.

Thanks for the feedbacks. Very nice to hear that you have correctly installed MapMint on your platform, it will be of big help for writing down the expected documentation and add the new modules to the project.

To activate the Tables and Importer modules you have to first load this inside your mmdb (it is the default name the installer is using, so it should be the name on your platform too): https://github.com/mapmint/mapmint/blob/master/template/sql/tables.sql

Once you have done that, you have to manually edit the main.cfg file and add this new key value pairs to the [mm] section:

importers=true
tables=true

In case you think this should be an option during the installation using this ansible-roles, please let us know by opening another issue on this github repository.

To install this version correctly, you must correct the configuration files:

Thanks, I feel that your last message should be another issue. Still, I will answer it here.

Many thanks for the updates, this modification has to be ported to the files you had modified.

For LibreOffice, even it is unfortunately documented nowhere, you require to run the scripts/loVersion.sh which download the page from LibreOffice official web site and parse the latest stable version available. This script should tell you in case you have to modify a file and which file it is. Please give it a try and report any issue or success using this script.

I think there were another issue that I have discovered when installing MapMint last week on various computer. Once installed, you should go in this directory mapmint-services/vector-tools-src and comment any reference to the service_yaml.o that should not be avilable due to the fact that yaml was not activated when building the ZOO-Kernel through the installer. This is my fault, cause I am use to have a ZOO-Kernel supporting the YAML format meaning that I had added those references to service_yaml.o and it never cause any issue on my side. Still, this have to be fixed. Can you please confirm that this was required.

[gfenoy]

If we refer to issue #1 then we can see the same modifications about the r-cran.xml file it seems.

Thank you M Fenoy, the issue has been corrected and I confirm that I have now all the modules. However I encounter other problems for configuring my tables

I often see this error message

Can you please let me know when this error occur ?

[ablayelana]

Mapmint has been updated but unfortunately this error occur

[gfenoy]

Please can you provide details on when does this error occurs ?

[gfenoy]

Thanks a lot for your feedbacks and for presenting when the error occurred.

Before being able to validate the form from the view panel you will need to provide a name (the title of your view) a clause (which can be set to true if not required) and you should also set value for both group and themes. So, your themes table should contains some element if you need to give access to the table you are currently configuring the view.

Hi Mr Fenoy
Thanks a lot. The table mansagement runs correctly now
However I encounter the same problem with the importer module
When you create the importer, you receive this error occur:

×Unable to load C Library (null)

×TRACE: No JSON object could be decoded <type 'exceptions.ValueError'> Unable to run your python process properly. Please check the following messages : [' File "/home/src/mapmint/mapmint-services/np/service.py", line 2069, in details\n ldesc=json.loads(outputs0[2]["Result"]["value"])\n', ' File "/usr/lib/python2.7/json/init.py", line 338, in loads\n return _default_decoder.decode(s)\n', ' File "/usr/lib/python2.7/json/decoder.py", line 366, in decode\n obj, end = self.raw_decode(s, idx=_w(s, 0).end())\n', ' File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode\n raise ValueError("No JSON object could be decoded")\n']

Hi,
can you please tell me what happen when you try to run the following command from a terminal?

cd /home/src/mapmint/mapmint-services/vector-tools-src/
make

In case the make command complains about service_yaml.o, then please remove any reference to this file from the Makefile in this directory and run make commande.

[ablayelana]

Thank you Mr Fenoy
I removed any reference service_yaml.o to this file from the Makefile and executed the make command but the error persists:

Hello everybody !

I come to give you a solution for those who have had to encounter these kinds of error when using the tables and importers modules

Unable to run the Service. The message returned back by the Service was the following: An error occured when processing your request: column "tablename" of relation "pages" does not exist LINE 1: INSERT INTO mm_tables.pages (name,tablename,type,ofield,otyp... ^ Traceback (most recent call last): File "/home/src/mapmint/mapmint-services/np/service.py", line 3085, in insert cur.execute(req) ProgrammingError: column "tablename" of relation "pages" does not exist LINE 1: INSERT INTO mm_tables.pages (name,tablename,type,ofield,otyp... ^

Unable to run the Service. The message returned back by the Service was the following: An error occured when processing your request: column "isreference" of relation "pages" does not exist LINE 1: ...ages (name,tablename,type,ofield,otype,length,iid,isreferenc... ^ Traceback (most recent call last): File "/home/src/mapmint/mapmint-services/np/service.py", line 3085, in insert cur.execute(req) ProgrammingError: column "isreference" of relation "pages" does not exist LINE 1: ...ages (name,tablename,type,ofield,otype,length,iid,isreferenc... ^

Correct the mm_tables.pages table structure ( https://github.com/mapmint/mapmint/blob/master/template/sql/tables.sql)

CREATE TABLE mm_tables.pages(
id serial NOT NULL,
name text,
tablename text,
type integer,
ofield text,
otype text,
iid integer,
length integer,
isreference boolean,
CONSTRAINT pages_pkey PRIMARY KEY (id),
CONSTRAINT pages_iid_fkey FOREIGN KEY (iid)
REFERENCES mm_tables.importers (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE CASCADE,
CONSTRAINT pages_type_fkey FOREIGN KEY (type)
REFERENCES mm_tables.page_types (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE CASCADE);
