I'm new to React Native and, in fact, even to development, because I've never been a developer before. I've been learning for a few months and I have some app ideas.
So ... because this is my level and I really don't know how I could do that, please don't hate me, I just want to ask you about this.
I would like to build something similar to a list of activities, but “aware of the time”. For example.. I would like to have a new list of activities with the same tasks every day. If it is 23:59, the progress made that day will be saved in the database, and at 00:00 a new list will be generated for the new day. If the user does not use the application for one, two or three days, the "empty progress" will still be recorded.
So.. again, please don't hate me, I think that would be the backend part. What can I use with React Native to achieve this type of behaviour and how?

I am trying to design an app (mobile + web) that displays random items stored in a database to the Users.
The issue I have is that I do not know how I should design such a database. The idea is that all users are logged in to use the app and that they get random items on the screens and can then swipe to the next one. The app should keep track of all the items that the user has already seen and never ever show them again. You could think of it as a similar app then Tinder but its not for dating.
I know how I should structure my database to store the items but I do not know what the best practice for such a use case would be. Should i create the complete items database for every new User and then delete the items from it that they have already seen? Or is there another (better) way to do this ? I can't really think of another way for now and my Project is stuck on this crucial part.
Many thanks in advance for any suggestions :)
I started modifying/developing Rally apps about a week ago using the existing Rally apps provided on the Github repository so far. However, for one of my final tasks I've been asked to recreate a tailored Defect Trend Report App and unfortunately, the source code is not available for the App. I tried to start from scratch but I've ran into numerous errors and am a bit overwhelmed.
I was wondering if anyone had the src code for the app or knew of a way to extract the src code from the existing app. Of course if there is custom code that an individual has worked on that could also help me progress in this process and wouldn't mind sharing it, that'd also help a ton.
I saw that there were a few snippets that could be used from the Hackathon repo, but they're not quite on the mark of what I want to do with the app. I'm just trying to have the existing app filtered by delivery versions (currently filtered by iteration/release).
All help is greatly appreciated.
Thanks fellas!
There is an example of a 'bare metal' chart app in the App SDK 2.0 docs. It should give you the basics on how to do a chart.To get to it, go to the help pages (click on avatar in top right corner) and search for "Rally App SDK"
After that, you need to work out how to select defects from the various releases and do a count of each. There are two ways to do this:
Get all defects in the project you are in (don't forget whether you need to scope down to child projects too) and then do something like _.uniq() on the release field to find the list of releases (or do another request to get all the releases into a different store and use that for names and a count).
Get the releases and then for each release request the related defects.
If you do ask for child projects, you will need to handle all the scenarios of different releases for different projects - can get complicated!
#1 is effectively one big fetch, #2 may be many smaller ones.
You may want to decide whether to count all defects, sum the estimates, ignore those not finished, etc., etc.
I wonder if it's possible to sum up a user's scheduled work hours?
I have customized the user entity and added a field that I want to show the user's total defined work hours in for the current week. But I don't know how to access the entity containing work hours. The problem is that I'm in an online organization and I can't access the database.
I've tried downloading SDK and of course googling. Since I'm a beginner I haven't found anything useful.
I've found an example for selecting time spans of working hours of a certain user. It's found in the SDK but, given that the example is written as a console application in C#, it might be perceived as complicated an unnecessarily complicated.
Also, it's mentioned that there's a field on the user entity, I assume that for this particular task, JavaScript might be more suitable and such an example I haven't seen.
This page presenting the source code is on MSDN. The bottom line is that you create a service and then execute the below.
QueryScheduleRequest scheduleRequest = new QueryScheduleRequest
{
ResourceId = GetRegardedUserId(),
Start = DateTime.Now,
End = DateTime.Today.AddDays(14),
TimeCodes = new TimeCode[] { TimeCode.Available }
};
QueryScheduleResponse scheduleResponse
= (QueryScheduleResponse)_serviceProxy.Execute(scheduleRequest);
For more information on how to handle the requests to scheduling and working hours see this article and for service appointments look over here.
I am looking for a way or a plugin so that trac sends me email about the number of new or closed tickets (and some information about these tickets also ) for a specific duration lets say for the last three days.
Basically I need to know how many tickets have been created in last week and how many of them have been closed at the end of week.
Of course the email only should be sent to the admin and not to all the users.
For additional Trac funcionality we have Trac plugins, yes. And the first place to look for them is trac-hacks.org .
The excellent TagsPlugin in use overthere already delivers some hints on resources tagged with notification or notifications. The most comprehensive and mature solution is certainly TracAnnouncer with a just reworked configuration interface providing a highly sophisticated opt-in and opt-out subscription system. Unfortunately digest notification are not integrated today.
Still there are other plugins, that fill in the gap, i.e. check the XMailPlugin. It claims to do configurable instant, daily and weekly notifications, so this may be for you. Since this is a relativly new plugin, you should expect some pending issues, but the author might be very open to your suggestion. If you're becoming a heavy user giving valuable test feedback and a bit lucky too, asking kindly could be enought to make things happen.
There's a slightly different way to solve this problem that doesn't require any plugins. First, create a custom "timeline" view that displays the information that you want. In your example, this would be all "opened and closed tickets" starting from "today" and going back three days. When viewing this custom view, you should see a link at the bottom of the page that says "RSS Feed" (on my system, the resulting URL looks something like this: http://myserver/timeline?ticket=on&max=50&authors=&daysback=3&format=rss). Click on this link to subscribe to the feed using your web browser, email client, or other program capable of reading feeds. Now, you can view the results live at any time. What you can do at this point is only limited by the capabilities of your feed reader app, but most can at least be configured to notify you when the feed is updated.
I have 2 1/2 years experience of VB.Net, mostly self taught, so please bear with me if I seem rather noobish still and do not know some of the basics. I would recommend you grab a cup of tea before starting on this, as it appears to have got quite long...
I currently have a rather large application (VB.Net website) of over 15000 lines of code at the last count. It does not do retail or anything particularly complex like that - it is literally just a wholesale viewing website with admin frontend, catalogue / catalogue management system and pageview system.
I don't really know much about how .Net applications work in the background - whether they are all loaded on the same thread or if each has its own thread... I just know how to code them, or at least like to think I do... :-)
Basically my application is set up as follows:
There are two different areas - the customer area and the administration frontend.
The main part of the customer frontend is the Catalogue. The MasterPage will load a list of products but that's all, and this is common to all the customer frontend pages.
I tend to work on only one or several parts of the application at a time before uploading the changes. So, for example, I may alter the hierarchy of the Catalogue and change the Catalogue page to match the hierarchy change whilst leaving everything else alone.
The pageview database is getting really quite large and so it is getting rather slow when the application is first requested due to the way it works.
The application timeout is set to 5 minutes - don't know how to change it, I have even tried asking this question on here and seem to remember the solution was quite complex and I was recommended not to change it, but if a customer requests the application 5 minutes after the last page view then it will reload the application from scratch. This means there is a very slow page load whenever it exceeds 5 minutes of inactivity.
I am not sure if this needs consideration to determine how best to split the application up, if at all, but each part of the catalogue system is set up as follows:
A Manager class at the top level, which is used by the admin frontend to add, edit and remove items of the specified type and the customer frontend to retrieve a list of items of the specified type. For example the "RangeManager" will contain a list of product "Ranges" and will be used to interact with these from the customer frontend.
An Item class, for example Range, which contains a list of Attributes. For example Name, Description, Visible, Created, CreatedBy and so on. The form for adding / editing loops through these to display relevant controls for the administrator. For example a Checkbox for BooleanAttribute.
An Attribute class, which can be of type StringAttribute, BooleanAttribute, IntegerAttribute and so on. There are also custom Attributes (not just datatypes) such as RangeAttribute, UserAttribute and so on. These are given a data field which is used to get a piece of data specific to the item it is contained in when it is first requested. Basically the Item is given a DataRow which is stored and accessed by Attributes only when they are first requested.
When one item is requested from a specific manager is requested, the manager will loop through all the items in the database and create a new instance of the item class. For example when a Range is requested from the RangeManager, the RangeManager will loop through all of the DataRows in the Ranges table and create a new instance of Range for each one. As stated above it simply creates a new instance with the DataRow, rather than loading all the data into it there and then. The Attributes themselves fetch the relevant data from the DataRow as and when they're first requested.
It just seems a tad stupid, in my mind, to recompile and upload the entire application every time I fix a minor bug or a spelling mistake for a word which is in the code behind (for example if I set the text of a Label dynamically). A fix / change to the Catalogue page, the way it is now, may mean a customer trying to view the Contact page, which is in no way related to the Catalogue page apart from by having the same MasterPage, cannot do so because the DLL is being uploaded.
Basically my question is, given my current situation, how would people suggest I change the architecture of the application by way of splitting it into multiple applications? I mean would it be just customer / admin, or customer / admin and pageviews, or some other way? Or not at all? Are there any other alternatives which I have not mentioned here? Could web services come in handy here? Like split the catalogue itself into a different application and just have the masterpage for all the other pages use a web service to get the names of the products to list on the left hand side? Am I just way WAY over-complicating things? Judging by the length of this question I probably am, and it wouldn't be the first time... I have tried to keep it short, but I always fail... :-)
Many thanks in advance, and sorry if I have just totally confused you!

Richard
15000 LOC is not really all that big.
It sounds like you are not pre-compiling your site for publishing. You may want to read this: http://msdn.microsoft.com/en-us/library/1y1404zt(v=vs.80).aspx
Recompiling and uploading the application is the best way to do it. If all you are changing is your markup, that can be uploaded individually (e.g. changing some html layout in an aspx page).
I don't know what you mean here by application timeout, but if your app domain recycles every 5 minutes, then that doesn't seem right at all. You should look into this.
Also, if you find yourself working on various different parts of the site (i.e. many different changes), but need to deploy only some items in isolation, then you should look into how you are using your source control tools (you are using one, aren't you?). Look into something like GIT and branching/merging.
