@sunbiz I have some doubts regarding our codebase. 1. I think initially you had made one repo [iupui-soic](https://github.com/iupui-soic)/ [mHBS-trainer](https://github.com/iupui-soic/mHBS-trainer) and in its master branch you are coding for trainer app in HTML, CSS & JS and in [mhbs-alpha](https://github.com/iupui-soic/mHBS-trainer/tree/mhbs-alpha) you are coding for tracker app which is cloned version of origin dhis2 app and you had made changes in it for mhbs tracker app. And later on, I think this mhbs-alpha get shifted to a new repository [iupui-soic](https://github.com/iupui-soic)/ [mHBS-tracker](https://github.com/iupui-soic/mHBS-tracker). Am I right? Please correct me if I am understanding wrong. 2. I think that the master branch of [iupui-soic](https://github.com/iupui-soic)/ **[mHBS-tracker](https://github.com/iupui-soic/mHBS-tracker)** is not up to date we had merged it with the new dhis2 app and shifted this repo to GitLab. Can you tell me the branch where the other work are done before and are updated if exists so that I can merge that with our updated GitLab master branch then we can check for all issues. Currently, I am not seeing any commits for the issues you have mentioned I think they are not merged. ---

@sunbiz currently as stated earlier I had shown the document in a list and Now I had added support to play video media files within our app and it is working fine. But I am not getting what do you mean by > [@sunbiz](#): > > Then it should be viewable through the app once someone is offline. do you mean that whenever a user is online we will refresh or download all the video media files from the server and store them locally and will be shown when the user is offline. But I don’t think it is right to download all media files from the server and store it locally on the device without user permission as if we have a lot of files on the server then downloading them over and over consumes a lot of data and even the storage space as may be user doesn’t want all video to be stored locally. I suggest that there is a download option in every media files from where a user can download a particular media file that he wants to be present offline instead of downloading all videos. And for the list of documents that particular data will not consume much space and internet we can directly store it locally to be present when a user is offline. So that the list of documents will be refreshed whenever the user comes online but to view a media either it should be downloaded by the user before or the internet connection should be alive. Please give your point of view on this. ---

This weeks blog [Third Week of Coding : 19 June - 25 June](https://bhavesh3005sharma-gsoc21.blogspot.com/2021/06/third-week-of-coding-19-june-25june.html) @sunbiz we have 2 ways to upload media on dhis2 one is files upload and the other is an external link. For files upload media if we hit an API call we get back a response of blob object and I am showing this in our app. But the problem is with files uploaded as the link they will give us an HTML response while hitting the API and for some of the files the origin link is directly available and in some of the files it is not directly available, I had checked it. And in fact, if we somehow manage to get an original link from that HTML response then the problem is that its uses depend on the type of link it is. As like if we simply post a youtube video URL on the dhis2 and get it in the trainer app even then we need some extra things to put on in the iframe, similar is the case if it’s a link of google drive and all. The point is that try to upload media as a file on the dhis2 to get it to work properly on the trainer app as it expects a blob object. And for the link, we are not able to download the content. You have to provide me with download files of these videos [Webinars (aap.org)](https://www.aap.org/en-us/advocacy-and-policy/aap-health-initiatives/helping-babies-survive/Pages/Webinars.aspx) if they needs to uploaded on the dhis2. I had sent an MR with this work please have a look [Added mediaPage and Populated with real data Fetched from bmgfdev instance and Added support to play all media files of type blob (!194)](https://gitlab.com/librehealth/incubating-projects/mhbs/mHBS-trainer/-/merge_requests/194) For offline support, I had decided to use the SQLite database and will be sending a separate PR for that. ---

@sunbiz Work related to offline support or SQLite is completed. I had created an MR ( [Link](https://gitlab.com/librehealth/incubating-projects/mhbs/mHBS-trainer/-/merge_requests/195) ) please have a look at that. I had made small changes in the UI as well to show the synced status of the documents. And the SQL database storage logic is also modified from one discussed in the last blog because we need to take care of the updates ( deleting a document from dhis2 & updating the name of document ) related to the documents, so to take care of them I had modified my logic. I had well-commented everything in the comments. Please have a look at it. And we have one more MR pending ( [(!194) ·Merge requests ·GitLab](https://gitlab.com/librehealth/incubating-projects/mhbs/mHBS-trainer/-/merge_requests/194)) please merge it before and then the offline support one. The new one has modifications on the files committed on the previous one to make the files available offline. I had added Gitlab- CI to the project as well and both MR has passed that one. ![454545](https://forums.librehealth.io/uploads/default/original/2X/2/25ac3be3007e4566a6611a37cc7cb754ea9b01a5.jpeg) ---

Even our past code which builds successfully over GitLab CI is not building now showing the same error I had find out a possible cause for that please let me know is it correct.

Is it right because this appears from today only? I want to discuss some points for the app usage tracker also. Currently, I had made [Page Usage Tracker](https://bmgfdev.soic.iupui.edu/dhis-web-maintenance/index.html#/edit/programSection/trackedEntityType/SVdH3LGkSru) tracker entity type and [mHBS Trainer Usage Tracker](https://bmgfdev.soic.iupui.edu/dhis-web-tracker-capture/index.html#/?program=mhGTULFgeuS) program to track usage. For every page, I had made a tei in this program and it will keep a record of total visits by all users & time spent by all users. For the page visits and time spent on-page in the app, I had made a new SQL table to store data locally and I will keep updating its visits and time spent for every page on user’s action. Now I have a doubt should we send this data continuously to dhis2 means every time when users visit the page update it to dhis2 or we can do it in a way like when visits in local DB become greater than 50 ( or some threshold value ) we will update it to dhis2 will make fewer API calls and saves a lot of data for users. Similar for time spent on each page. And I want clarifications about the login system of the app. I think there is not any login screen in the app. How the users enter the app? Till now the overall usage of the app can be tracked but to track usage over per user we need total users of the app. ---

For every page, I had made a tei in this program and it will keep a record of total visits by all users & time spent by all users. This will be too much data and so we should likely not have separate tracker entity type for this purpose.

I know the initial design was like that, but I think it was suited for a research study where we wanted to discover how app usage affected training outcomes, for multiple apps. Now that we want to scale this, I think it is better stored and tracked through user attributes ( ` /api/33/userDataStore`), rather than a separate program. > [@bhavesh3005sharma](#): > > Now I have a doubt should we send this data continuously to dhis2 means every time when users visit the page update it to dhis2 or we can do it in a way like when visits in local DB become greater than 50 ( or some threshold value ) we will update it to dhis2 will make fewer API calls and saves a lot of data for users.

@sunbiz did you mean that in users datastore we should store the app usage of the trainer app by every user. What I had understood is for every page I will create a namespace in the user’s datastore and key for elements like page visits, time spent, etc and update their values there in JSON format. Is it right to mean I should implement it in that way? And one more point in this way we can track the usage by each person but I think we need the overall app usage as well how we can do that in this? or usage for every person is enough to be recorded an we can left overall usage? ---

@bhavesh3005sharma this is one of those issues that doesn’t have to be solved urgently. It would be good to find a generic solution, but there is a workaround from the DHIS2 side by limiting the search for certain user roles.
