just as a heads up I am 100% new to salesforce, only hearing about it yesterday. I have been assigned the task of writing an API to pull customer emails into our new website that is currently on my local host. I know the sobject name of the emails is a string called emails. However I think I am missing some major fundamentals despite reading a bunch of salesforce documentation pages.
When I log into our site I do not see a database (like I would have expected) I just see the many objects for our cusomters. I just can't seem to understand where I am supposed to write this "api" that I was told to do, or how to use it once it is written somewhere. I apologize for having no clue what I am doing regarding this, can someone please explain the basics of pulling data from it (currently on windows running apache if this matters, using HTTPS).
Probably, you will need to implement REST API services on Salesforce side and work with them from your app. If you are totally new with Salesforce just try to read Learn Salesforce Basics or use Trailhead interactive courses.
When you will understand a bit SF, you will need to learn how implement Salesforce REST API, here is the related documentation.

I want to implement an evaluation feature to my chatbot. User would be able to rate service on a scale of 1 to 5 and make suggestions.
I guess I would use slots for that and store the provided data in a variable.
What would be the easiest way for me to save and access that data later?
Somehow I need to write it to a database and make that database easily accessible. Or ideally having Watson sending an email with the feedback to myself.
Is there an IBM Cloud Database service available for that?
What would be my first steps in order to achieve this? Maybe you have some tips or documentation links, or even code snippets if it's not to much work for you.
I used IBM Cloud functions to get a joke from an API to Watson via webhook. I used code from the internet. So I am somewhat familiar with the concept, but I need more guidance and couldn’t find anything helpful. Basically I know nothing about NODE.
I would recommend the tutorial and its code on how to build a database-driven Slackbot with Watson Assistant. It uses a webhook and Cloud Functions to interact with a database for various actions. You could use that as blueprint for setting up the webhook and see how the database is invoked.
Make sure to secure the webhook. This can only be done using the command line (CLI), see the Cloud Functions doc on securing web actions.
I would like to ask how to create an ionic app that talks to Laravel API but still works offline when there's no connection.
Let's say i have to write a quiz mobile app in Ionic and it requests for Laravel API to retrieve the questions as well as store the scores in db.
I'm just starting to learn Ionic and i'm really confused right now on how to approach this.
What confuses me most are:
Does the Ionic source live inside the Laravel source code w/c serves the API?
If i want the Ionic app to be installable, should the Laravel source code be included as well during the compilation process?
Thanks in advance for any help.
Your php or in general server side code is completely independent from your ionic application. If you want your app to work offline you should think about something like fetching a high number of information initially and work with this data without making any additional requests.
However your ionic app does only contain the frontend. You could implement some logic for local storage, but if you want to keep information hidden from the user (e.g. solutions) you have to put that logic on a dedicated server.
In the few details you provided, I can say the Laravel code does not live inside the ionic app. The ionic app is separate from the backend API by Laravel. You are possibly trying for a ReST based architecture where you communicate with your Laravel Server with an API. You need to keep those codes separate.
However without any internet, you won't be able to access those APIs, so you will just be able to show some static data, or you could serve from a DB and show later. For how to use the sqlite db you can look here
In your backend you can have an API like
http://example.com/api/v1/questions/1/
Which will fetch a question with options and if you want the app to have the answer for offline storage you may have that as well. When a user answers, you may check whether you have internet access and send answer and verify if you do, else you may save the answer in your DB and sync when you do have access. You can fetch multiple questions so that a user may answer multiple questions in case he/she will not have internet access.
Hope it helps. :)
I am trying to develop a web application that can communicate with another web application. App1 is an app developed using Angular.js and Struts2. This apps sole purpose is to perform search queries on several databases and returning the information about the products for the user to view. App2, the current app I am developing, will be developed using Angular.js and Flask/Python. This app will be responsible for storing the products the user selects in a shopping cart and allowing the user to make a purchase.
I am stuck as to how to get the two applications to communicate(passing login information, selected items ids, etc.) with eachother.
I have tried passing information via a url redirect (http://www.example.com/?myVar=someData&...) but Angular is giving me a lot of trouble to try and get around that. Even if I can get this to work, I think it would be insecure as data the user shouldn't know will be exposed in the url.
My second thought would be to somehow access the session data from App1 in App2 but that could also lead to security issues.
My final thought would be to some how make a call to App1 that returns a json object that can be parsed in App2 but I am not entirely sure how to pass that information along.
How can I get the two applications to communicate with each other?
Thanks for your help
In my opinion this isn't really within the scope of AngularJS. However, I believe that the best, most accepted practice for communication between web applications in this day and age is RESTful Web Services.
It's not a small topic, but once you get the concept behind it you can use it in any programming language that supports web applications (Java which I'm assuming you're using because of struts has multiple REST libraries, I prefer Jersey but that's just me).
It's also an amazing way to use your Angular front end to talk with its own back end. The entire Angular $resource framework is built around the idea of using RESTful services.
Check out this link on Wikipedia for a brief synopsis of what makes a service RESTful: http://en.wikipedia.org/wiki/Representational_state_transfer#Applied_to_web_services
Now, that applies to most of what you asked. As far as login information is concerned, that's going to depend on your security implementation. A lot of times you can put information like that in the header of a web services request, and only accept requests that come from trusted servers, etc. but there's a good bit of stuff to understand there. It's an entirely separate topic.
Hopefully this helps you get started. Let me know if you'd like more information or pointers.
I am doing a survey about cloud paltforms and I have the following the question:
Is it possible to upload a Java/PHP/Python/etc application on Force.com just like you can do with Google App Engine, Heroku, Openshift, etc.?
I looked at the Salesforce website but I couldnt reach a certain conclusion. If I understood correctly, you can upload the code on Heroku and then integrate the application with features of Force.com or something like that.
Could someone shed some light here? Thnx
Force.com has his own language to run custom code on server. This language is called APEX.
Apex is a strongly-typed, object-oriented programming language that
lets you centralize and execute flow and transaction control
statements on the Force.com platform in conjunction with application
calls to Force.com APIs. Using syntax that looks like Java and acts
like database stored procedures, Apex lets you add powerful custom
business logic to most system events, including button clicks, related
record updates, and Visualforce pages. Web service requests and
database triggers on objects can also initiate the execution of Apex
code.
More info in the official apex doc
But you can't upload to salesforce servers any kind of standard code like php/python. If you need to develop your own app using php/python/java + salesforce-api's you will have to upload/run this code on your own server.
Heroku and database.com are closer to what you're after. Heroku will let you upload you Python/Java etc. app and then you can easily connect it to Salesforce-style database.
By "style" I mean one in which you can still use this Apex language in triggers for example or expose pieces of Apex to be called via webservices. Such webservices could be used like "stored procedures" in classic solutions - if you'd want to keep part of the logic on the Force.com side rather than in your app.
Martin's answer is very good. If it's not immediately obvious - there's a "vendor lock-in". You can't run this Apex code anywhere else, only on SF server. There's no open source equivalent like LAMP stack for PHP, Tomcat for Java etc.
I think it will make sense for you to read these 2 questions from "related" sidebar: Disadvantages of the Force.com platform and
https://stackoverflow.com/questions/3363333/anyone-moved-off-force-com. They're a bit negative but for your pros/cons type of comparison should give you some highlights.
I want to use Google Prediction from a Python Google App Engine Application. Google Prediction requires you to store your "prediction models" in Google Storage for Developers, in effect meaning that to use GP you must use GSD. Unfortunately, both GP and GSD seem to require OAuth 2.0 .
This Oauth stuff is really getting in the way though! All the examples I find seem to deal with the case of wanting for access a users data/credentials/identity/whatever using Oauth. I have no need for that. I simply want to access a resource (GP and GSD) from my server using http request. Repeat, I just want to use some of their services, I have no need at all to access any other users information!
I can see from my Google API console that I have created both a id and secret for my GAE applications domain. Is it not possible to just use these values to do OAuth authentication to other Google API's? Effectively saying "I am the application at domain xyz, here are my credentials, let me use your API"? It seems kind of ridiculous that Google is currently forcing people to use such a burdensome authentication system for things that they are trying to get people to try out?
I am hoping there is some magical awesome library that will take care of all these OAuth details for me. Short of that, a code example of how to do these things in Python App Engine would be useful. I just want to use the Google Prediction and Google Storage for Developers services from my python GAE app, but I am blocked by the burden of having to configure all of this OAuth stuff. Isn't there some easy way to do this?
Look at the Google API Python Client. You should just be able to put your tokens in and connect. There are some examples on the page that should give you enough information to connect in.
I'm the Product Manager at Google working on the Prediction API. The first thing I want to say is thank you for trying out the API and for reaching out to the world about your issues! We hear you! We are very aware of the difficulty of using the API in some cases and some of the pain OAuth2.0 can cause for the simple use cases. In particular I tried to do exactly what you were doing a few weeks ago and was myself rather frustrated! We're working on it!
OK, so, that's all nice and dandy, but do I have anything helpful for you? Hopefully I do! I managed to get my GAE application working with GP -- I shelved the GSD component for the moment as I ran out of time, so hopefully somebody else can lend you some sample code for that (it should involve using boto & OAuth to handle the tricky bits).
from apiclient.discovery import build
from oauth2client.client import OAuth2Credentials
# You can find an example oauth2client in the python prediction sample code
# Replace everything in <>'s
credentials = OAuth2Credentials(
"<access_token>", #probably empty string
"<client_id>",
"<client_secret>",
"<refresh_token>",
<Expiry>, # Probably None
"https://accounts.google.com/o/oauth2/token",
"<app_useragent>")
http = credentials.authorize(httplib2.Http())
service = build("prediction", "v1.3", http=http)
You should be able to get the client id an client secret from the API console. You can use any sample application or demo, e.g. the python sample code, to generate a refresh token.
Best of luck! Feel free to followup directly with me (zg#google.com) or post to our public discussion list (prediction-api-discuss#googlegroups.com) if you still have any trouble.
