Gustavo Bellino BellyBest has launched its Beta version

The following text was translated by Google Translate Technology

BellyBest is a social network that allows its users to search restaurants by area (geolocation), upload their favorite foods, vote othe foods, and primarily allow to interact with people with similar tastes. The social network has its iPhone version (as they advance in development) and it is maturing and gaining ground in its area. The features that are currently released in BellyBest are limited as it is in the beta version. However, we think that by the end of this year the social network will be mature enough to show the world all the features that the Keetup team has developed.

Once again we are proud to be part of a big project and we thank the entire Keetup team that made it possible (converting the social network and the API for iPhone application to life).

We wish the best for the people of BellyBest and thank you for choosing us to develop the engine of your social network.

Diego Gallardo Talk about Elgg features in Barcamp Rosario

The following text was translated by Google Translate Technology

On 3 September, the first Barcamp Rosario was held at the Universidad Abierta Interamericana (UAI). There are already two such events taking place in the province of Santa Fe, along with the Barcam Litoral held in May this year.

In Keetup we really like to attend such events, so we were present.

Attended the event with high hopes of witnessing several talks, but the slower people call, there was a very significant amount. Of those who attended had a very good quality.

At first we were not going to make a presentation as we went with the intention of being just spectators. But after seeing that there were few conversations at the event, decided with Gustavo (@ gushbellino) scored to give one talk about Elgg, titled "Elgg, The Social Network".

The talk was quite descontracturar, with several questions and answers as we gave the presentation, and some examples of the benefits of Elgg. As the data model and the abstraction of the database for the programmer.

Here I give the presentation:

We also have footage of the same charge of @ PabloVerano.

I leave 2 of the 4 videos of the presentation:

Elgg Happy Coding

Diego Gallardo Elgg Data Model

The following text was translated by Google Translate Technology

Elgg provides a data model that allows us to abstract away completely from the database.

Provides a unified data model called the Entity-Attribute-Value (EAV), which is based on atomic units of data called "Entities".

As you can see in the picture, everything is based on Elgg Entity (ElggEntity).

Users are entities, the groups also are entities, including the site itself, is an entity.

There are 4 types of entities that are specialization of the principal ElggEntity are:

  • ElggUser (Users): All users on the site are ElggUser an entity type.
  • ElggSite (Site): The site is an object with its properties.
  • ElggGroup (Groups): In an entity that contains / groups other entities. One group is made up of members which are users. May contain different entities, such as blogs, files, forums, which are created within the group.
  • ElggObject (objects) in any other social network content is generated by an object. Example objects are blogs, files, bookmarks.

Through these 4 entities can model any type of functionality in Elgg. These specific entities, have their class and related functions.

These entities can be extended to add information to them in 2 ways:

  • Metadata (Metadata): Metadata are properties that can be assigned to an entity. Adding additional information to it. For example, if a user can be date of birth or nationality.
  • Annotations (annotations): annotations are used for feedback on an entity. For example, when talking about a blog, comments and ratings to the blog, are annotations.

A clear example between annotations and metadata are:

  • Metadata are unique properties of an entity, in this case, only the creator of that entity has the ability to assign.
  • The annotations are the feedback provided to the entity, any user can perform. The notes also have defined roles for the sum, amount, or their average.

Entities can also relate to each other and relations are directional. To create a relationship requires a relation name and two entities.

An example of one-way relationship is when a user is a member of a group, establishing the relationship, 'member' between user and group.

An example is two-way relationship is friendship, which creates a relationship of friendship from the user 1 and user 2 and vice versa.

Any new functionality we will be modeled by these entities. The methods and functions which include persistence and access to data from the database. Means that it is more necessary queries manually, or having to create new tables when we need a new feature on the site.

I hope you liked this post.

Happy Coding Elgg

Diego Gallardo How to test Elgg features with different users in an easy way

The following text was translated by Google Translate Technology

Many times in Elgg we test different features of the plugins with different users, whether performing tests of content from friends, permits content or simply try a multi-user functionality.

It is sometimes difficult, as we should have open multiple instances of the social network in different browsers with different users, or logearnos and offline all the time.

A quick and simple to accomplish this is to install the plugin Login as developed by Brett Profitt. This plugin allows, when you're logged in as administrator, can login with other users, and then get back to the administrator. All this without logout of the site.

This makes it much simpler to perform this task.

We can download from the community the following location: http://bit.ly/pLgT7h

After downloading and unzip the mod folder, we must activate it.

1. Let the administration section of Elgg:

2. After the administration section of tools:

3. We will activate the plugin:

4. Then we entered the list of site members to login with a user.

5. By clicking on the shortcut menu, a user can see the "Login as" allowing that user login.

6. Also when entering the user profile that is the option "Login as".

7. Once we make the "login as" that user, we see that we will not have more management options in red, the user profile:

8. Also in the topbar of elgg appear 2 icons of users, to the left of the user that performed the "Login as", then an arrow and the admin user logged-in we were before. To return to the admin user, simply make one click on the icon of this person.


I hope you liked this post, and have been used this plugin simple but very effective in developing new features in Elgg and can test them with different users.

Elgg Happy Coding.

Diego Gallardo Elgg site path and database configuration

The following text was translated by Google Translate Technology

In this post we will learn how to manually configure an installation of Elgg. This type of configuration can be realized, when you migrate an elgg site, when you install a site where there is already configured with the db users and data, or when there is a problem with the installation and we work our site Elgg.

I will go on to explain where you set up an elgg installation through the configuration file to access the database and also the path and url of the site in the database.

This type of configuration in the elgg installation page, but it's always good to know where these settings.

In this example we will set up a site called "elggbase."

The base configuration file located in elgg "elgg / engine / settings.php"

If you do not have the settings.php file, you can copy the template file "elgg / engine / settings.example.php" and rename it to settings.php in the same folder.

Editing the settings.php file, copy recently, I find as follows:

In this file we will set up data access to the database (user, password, db name, host, prefix), changing the values ​​contained in braces "{} {}" which would be as follows:

Once we make the configuration of access to the database, we will set the path of elgg in the database, for this we should have access to phpmyadmin on the database. Assuming you already have the database installed and the name elggbase.

Once we access the database, we have set the path where the installation of Elgg and Elgg data path, this is the path where you installed the site. It depends on each server, but usually in "/ var / www" or / home / myuser / public_html "elgg_datalist access the table:

We must change the path and dataroot values, in this case I locate the installation of elgg on the path "/ web /"

Something very important, always add at the end of the url / path the slash "/" as in the case that we forget it, our elgg site, it will not work.

Now we must configure the URL of our site, accessing the table elgg_sites_entity:

Now we must change the value of the url that will take our place.

I hope you liked the post, and have learned how to manually configure an installation of Elgg.

Elgg Happy Coding!
