4. Ruby On Rails
Right Choice

5. Mr. Amari Blue has recently developed his
business web app, which is a huge success,
using Ruby on Rails. He struggled a lot
during the making, planning, and execution
of his Ruby on Rails application
development, and finally, he is now reaping
the sweet fruits of his efforts.
Mr. Blue is glad that he chose Ruby on
Rails for his project because Rails is a
comparatively simple framework. Of all the
other advantages, he was benefited by
RoR’s high-speed MVP development, open-
source availability, free plugins, and
multiple platform-compatibility. His
development team was grateful for the
RubyGems because their development time
was reduced without writing excess code.
Ruby on Rails is, beyond any doubts, the
best framework for your project.

6. This experienced entrepreneur got more
time-to-market for his product because his
developers found Ruby on Rails for MVP as
a speedy development option and followed
the standard practices. He wanted to share
his experience developing a web project and
demystifying common mistakes in Ruby on
Rails development that young
entrepreneurs face. He wants to share Ruby
on Rails programming mistakes to avoid so
that he can appraise other businessmen to
learn from them.
We came up with this blog so that Mr. Blue’s
ideas reach other entrepreneurs out there,
and they can leverage from his experience
while developing their Ruby on Rails
project.

7. 05 Common
Mistakes in
Ruby On Rails
Development
by RoR
Developers

8. Every successful project has undergone its
pitfalls and experiences. During Mr. Blue’s
observations, there were several incidents
where he was like, “What is going on?
Everything seems like a mess.” Thankfully,
he was following the Agile software
development approach that he was always
able to track his Ruby on Rails project work
and get regular updates from his
development team.

9. At each successive stage of his project, he
made sure that he asked the Ruby On Rails
development team-lead, to sum up, their
experience and take notes. At the end of the
project, he reviewed what technical
mistakes could arise in a project and how
his Ruby on Rails developers can overcome
them.
Here, we have gathered the top 5 common
mistakes RoR developers make while
developing a Ruby on Rails web
development project.

10. ⦿Model
Mr. Blue mentions that developers tend to
put too much complex coding functionality
into the Model layer of MVC architecture.
He explains that the Model layer is meant
for your entire business logic, so you should
not make the mistake that most developers
do.
To build better Rails applications, you must
not include logic for email notifications,
data conversions, etc. in the Model. Spare it
for configurations like relations and
validations, simple mutation methods,
access wrappers, and sophisticated queries.
1. Stuffing Excess Coding
in Model, View, and
Controller

11. ⦿View
The View layer of your application is purely
for the HTML files and tags. Many
developers make the mistake of writing
database queries in the View, which takes a
lot of time to load your application. Such
practice should be avoided and instead
create view files that have partials to get rid
of duplication.
⦿Controller
Ideally, the Controller should contain
session/cookies handling, management of
parameters requested, redirecting, and
rendering views. For other tasks, developers
should not keep other codes in the
controller, which increases your app load
time.

12. Most of your Rails applications will be using
external services like Facebook, Google
Maps, AWS, etc. The credentials of such
external resources and their APIs are stored
in the credentials.yml or secrets.yml files in
your configurations. Now, Mr. Blue says
that the developers need to create a
separate account to provide security.
Otherwise, anyone who has access to your
repository can access all your users’
accounts.
RoR developers need to create a developer
account that keeps your configurations safe
against all the intruders.
2. Keep Your
Configurations Safe

13. RoR developers feel blessed because they
get an abundant number of gems for their
ease. However, Mr. Amari Blue mentions
that too much is not suitable for anything.
Some developers make excessive use of
gems in their applications to the extent that
gems’ usage is more than the app’s
functionality.
The first problem that arises from Gems’
excessive use is that your web app’s size
increases, which lowers the app
performance. Additionally, it needs larger
memory configurations and increased
optimization costs. Your Rails application
takes a long time to start, which also
reduces your development time.
3. Excessive Use of Ruby
Gems

14. Moreover, with each gem you include, you
invite a dependency on another gem, and so
on. You multiply the number of
dependencies in your application, which
creates lags in your application. This is the
compounding effect. For example, using a
gem rails_admin will create dependencies
for 11 more gems.
Hence, you should consider the overhead
before you use a gem.

15. Mr. Blue was amazed to know ROR’s
database migration characteristics, where
developers can manage the minutest
changes when their application gets stuck
with a problem. This functionality worked
well with his application development in
the initial stages.
However, soon he realized that in the longer
run, such database migrations are
challenging to handle. At that time, his
Ruby on Rails developers showed him the
right way to dump the old migrations
because they could no longer manage the
project database.
Hence, the entrepreneur advises that
developers should not get accustomed to
the lenient database migrations.
4. Accustomed Database
Migrations

16. Mr. Blue suggests that before developers
start to develop their Ruby on Rails project,
they should be clear with what type of Rails
application they are going to create. For
instance, whether it is a rails API, rails
service, or rails application.
Such standard practices of the developers
will ensure that the RoR project will have a
sound base. Setting up the basics initially
and then changing those mid-way affects
the development time and code quality.
5. Correct Rails
Application

17. Mr. Blue, our generous entrepreneur,
learned the above five common mistakes to
avoid from his Ruby on Rails project
development team. He is grateful that he
got such experienced Rails developers and
wishes that his learnings can help other
developers out there.

18. 07 Common
Mistakes by
Entrepreneur
s While
Building Ruby
on Rails
Project

19. Apart from the technicality, Mr. Amari Blue
has also learned a tremendous
entrepreneurial lesson after this project’s
success. He wants all the aspiring
entrepreneurs and his friends should know
what to do and not do while building a Ruby
On Rails project.

20. Mr. Amari Blue used to be very excited
about his Rails project. Since the beginning,
he used to interact with his development
team and ask for updates. He realized that
he is impatient. Thanks to his RoR
developers, they made him understand that
development is an intensive process.
He shares that he was expecting a lot in a
little amount of time. He tells fellow-
entrepreneurs that enthusiasm is good but
not to the extent that it starts bothering and
hampering your progress.
𝟙. Over-enthusiasm and
high-expectancy

21. Mr. Blue admits that he is an optimist who
always looks at the brighter side of any
situation. While his Ruby On Rails
development team was busy developing his
project, he couldn’t wait to check out the
end-results. He never even thought that
anything could go wrong, which is ideally
impossible.
Sometimes, he would get disappointed
when the outcome displays errors. This
experience made him realize the
importance of testing an application. Hence,
Mr. Blue strongly suggests not to ignore the
QA tests in your RoR project.
𝟚. Ignorance for QA
testing

22. Mr. Amari Blue had outsourced his Rails
project to a dedicated development team,
and hence communication was the only
bridge that kept him linked to his team and
his project. He says that when you hire a
dedicated development team, you get the
profile description of the company. Instead,
what you need is a personal encounter with
your development team.
Mr. Blue made sure that he organized
virtual meetings and sessions with his Ruby
on Rails development team and addressed
them with their first names. His mantra for
finding the right candidate for your
technical team is knowing your team and
communicating without any barriers.
𝟛. Lack of specific RoR
developer

23. Mr. Blue advises that before you hire your
onshore or offshore Ruby on Rails
development company, make sure that you
first take a trial period. It saves your time
and effort because once the project
development begins, it is a long process.
And later, when you realize that it is not
meeting your expectations, it is already
quite late.
𝟜. But trial first

24. Mr. Amari Blue was very friendly with his
development team. He kept no secrets,
which helped him notify the team of his
goals. He says that some entrepreneurs
treat their developers like their employees
and hence raise a wall between them. This
strategy may keep you in a reputable
position, but it doesn’t help you meet your
goals.
Once you are close to your team, they
understand your expectations, and it
motivates them to fulfill those goals as if
they are their personal attainments. Our
grounded entrepreneur, Mr. Blue, was
never hesitant to share his future
aspirations with his team. This action kept
the team strong and motivated towards
their goals.
𝟝. Hesitant with sharing
business goals

25. Hence, Mr. Blue suggests that business
people should not keep their goals unsaid.
Instead, they should speak them out loud so
that the universe knows and helps them
achieve the same goals with positive
energy.
𝟞. No agreement or
contract
The prime reason for Mr. Amari Blue’s
project success was his discipline and
standard procedures. Since the beginning,
he had made a significant contract with his
development company which mentioned:

26. Dedicated working hours of a developer
per day or per week.
Replacement developer in case of
absence or leave.
Bug-fixing costs.
Management and handling of bugs in
the future post-project-completion.
Notification duration in case of a
developer’s short-term or long-term
vacation.
Mr. Blue suggests that having such a clear
contract before signing your deal is a must-
have.

27. Communication is vital during your project
development process. Ideally, your
development team works as you say, and
you pay them for their work. However,
keeping them well-informed throughout
the entire project development phase is
essential, and not just at the beginning.
𝟟. Expecting developer
to understand the
entrepreneur’s point of
view without giving
feedback

28. Mr. Amari Blue says that telepathy is
astounding; mostly, it works magically
between friends and loved ones. But, you
should not expect your developers to
understand your perspective magically. You
have to coordinate with them, guide them,
and take regular updates and follow-ups to
be on the same page with their
development process.
With these seven pieces of advice, Mr.
Amari Blue feels proud that his experience
can acknowledge several other
businessmen on how to begin their startup
application development. And be prepared
to tackle the common mistakes in Ruby on
Rails development to meet aspired success.
